Your view seems to be close to gnostic scripture. The "evolution" according to that scripture (from my memory) seems to be that at first one divided itself, and mostly from this duad a "child" was born, so that we have a trias. This "child" then can function as a new creator of a second, lower level, or it contains this lower level.
There are some more of these hierarchic levels created, and at one point, on a lower level, somehow the "distance" to the source became so high and the love rays less intense that this lower sphere became impatient and started to create on it's own, soon regretted it, but the step was done, and so there was a low-level-creator, the demiurgos (Lucifer is one name for this character) who created the physical. Sometimes this creator is an evil character, sometimes not. Sometimes the creator works consciously to make the best of the situation, sometimes this creator thinks to work against spirit, but in truth is fulfilling the plan of the high spirit. The humans in the physical are a mixture of spirit and flesh. Humans have to become aware of the true spirit world and become aware of the falseness of the physical (for example the drives of the ego). The role of Jesus, who had been a perfected spark in spirit but came down into the physical to become a teacher, was to open the eyes of the people to the true world of spirit. The destiny of the physical world either is to break down from itself one day, or to be changed according to the true spirit world.

What's different to your view is, usually the physical world is described as something to turn away from as much as possible, and not to attempt to perfectuate the physical body. As far as I remember, in gnostic scripture the physical body of Jesus was just a physical body and died. But Jesus/Christ died not, as he had developed an eternal body because he was in tune with the high spirit. Those who achieve this will live forever in the world of spirit, those who not, will become unconscious and incarnate again into the physical.

That's what I remember is, in short, the story according to relevant gnostic scripture.

Spooky

I don't know if this relates, but a few days ago (May 24) I had dream that included a lady who was supposed to be Edgar Cayce's mom, and Justin.

The dream:

I'm outside and there is a lady who is the spirit of Edgar Cayce's mom. She looks as if she is a little younger than 40 years old. She's fairly attractive and has blonde hair. I'm suprised to see her as clearly as I see physical people.

Next,  I was inside of a ship. Justin is there, but I don't communicate with him.  Edgar Cayce's mom is there, but now she's a physical person, a reincarnation of her previous self. She looks the same as she did when I saw her outside, except that her eyes look spooky (no pun intended Spooky ).  Justin has a bookcase on the ship and I try to find a book about Edgar Cayce within the bookcase, so I can see what Edgar Cayce's mom looks like. I didn't find such a book.

Next, my sister, who in this dream symbolized the creative aspect of spirit, made a big pot of soup under some floorboards of the ship, and added ingredients according to the instructions Edgar Cayce's mom provided.  I tasted it, and it tasted awful.

Possible interpretations:

-The common viewpoint of reincarnation was negated in three ways: 1) the spooky look in and around Edgar Cayce's mom's eyes suggested that a reincarnation of herself didn't represent the truth; 2) such a way of creation was referred to as negative when my sister made an awful tasting soup under the ship's floor boards according to Edgar Cayce's mom's instructions; and 3) I couldn't find a verification photo of her in Justin's book case.

Going by what I figured after giving it a lot of thought, and going by the spirit messages I received, no self/probe incarnates more than once. Therefore, any one self gets stuck only to the extent of how long it takes such a self to return to its disk.  This approach suggests that the typical viewpoint regarding being stuck in rounds of reincarnation isn't true, unless you figure a disk gets stuck.  Since the majority of a disc remains in a place beyond focus 27 and is able to handle multiple incarnations throughout various periods of time, I find it hard to believe that such beings are actually stuck. Perhaps they have some issues to work out, knowledge to gather, and incarnating selves to assist so they can become a part of the party in a knowledgeable way, but stuck?

Just recently I asked for a confirmation that my way of understanding reincarnation is accurate, I heard a voice say, "For the last time," and was shown a couple of symbolic visual images that seemed to indicate that I'm correct.

The next evening, the same evening when I had the above dream,  I wanted to make certain that I interpreted the messages I received correctly.  I didn't receive a response.  I took this as a cue that I should trust my interpretations, and/or try to become more certain on my own.  I tried to do so, my awareness expanded, and I tuned into the feeling of how all generations of the human race happen at the same time, it just seems as if they happen at different times.  I recalled that both Rosalind Mcknight and P.M.H. Atwater had experiences where they experienced all generations of mankind happening at the same time.  This being the case, it isn't possible for one parcel of consciousness to incarnate over and over again, because all of its other incarnations are taking place while its incarnation takes place, the connection between the different incarnations exist at higher self/disk level.

I can't say I'm one hundred percent certain about the main subject Justin is talking about, but I basically believe that life in this World isn't a mistake, it's just that the learning experiment has gone astray.  Going by my night in heaven experience and a dream where I witnessed the end result with indications of how we proceed to this end result, I believe that despite our learning pains, every thing works out.

A part of things being better than they seem is the factor of how each self has to incarnate only once, rather than hundreds or thousands of times as some sources suggest. How much suffering and imperfection can one self stand?  It is no wonder that such a way of thinking sometimes advocates self anihilation.

Regarding the ship, sometimes ships in my dreams represent vehicles of learning, a way of trying to get to where we are trying to get.
