David Pinyana,
You have tried to incorporate all the existing mainstream ideas into a single framework. Different emergent properties at different scales is a possibility. If the physical world is like that we cannot do anything about it; we can only try to explain each 'landscape' using different set of axioms.
However you have limited the number of 'landscapes' to 20. Though this is more than enough to contain all our future discoveries, theoretically there can be infinite 'landscapes'. Any theoretical limit is arbitrary; but if observational evidence suggests any limit, then it may be real. As you concluded, if we believe in a lower limit, we can expect a TOE.
What I propose is 'Finiteness Theory', limiting the 'landscapes' to a finite number, just five. Obviously, it has a lower limit and is 'a Theory of Everything'. Newtonian physics with some modifications (not MOND), is enough to explain these five 'landscapes'. The modifications are, (i). motion at speed 'c' is a property of matter (ii). force is reaction to that motion. The essay I have submitted is based on this model.
