Your on "fundamental metaphysics" is very intetesting. It sounds very similar to CTMU, Cognitive Theoretical Model of the Universe. This model was theorized by Christopher Langan, one of the smartest people in the world, with an IQ between 190-210.
Here's a summary of the theory by the man himself:
Langan told Muscle & Fitness magazine that "you cannot describe the universe completely with any accuracy unless you're willing to admit that it's both physical and mental in nature"[12] and that the CTMU "explains the connection between mind and reality, therefore the presence of cognition and universe in the same phrase".[13] Langan contends that anything sufficiently real to influence reality must be within reality, and that mind and reality are ultimately inseparable to the extent that they share common rules of structure and processing.[14] He calls his proposal "a true 'Theory of Everything', a cross between John Archibald Wheeler's 'Participatory Universe' and Stephen Hawking's 'Imaginary Time' theory of cosmology."[4] In conjunction with his ideas, Langan has claimed: "You can prove the existence of God, the soul and an afterlife, using mathematics."[9]
He explains it further in this Q & A:

The article and Q & A are excellent explanations of his theory. The theory supports many of your claims, and goes deeper in some cases. Most of it is supported by sound logic. Are you familiar with this theory? If not please read that Q & A, I want to see if you disagree with him on anything, or have anything to add.
