Very good. Now you are down to the nitty-gritty.
"Where QM accepts instantaneity in an a priori discrete jump to effect an quantization, I would argue that a continuous variation of velocity is simultaneously existential in a discrete matter state."
There is really no instantaneity in QM, there is rather a time for the evolution of each excitation where matter and time represent a pure superposition of states that then evolve into two complementary matter waves with two complementary and coherent clocks. So quantum states evolve continuously just like classical states.
Moreover, QM rest and moving clocks combine into a proper time norm of experience just like GR, but those QM clocks can also interfere with each other, especially in some future action involving the moving clock complement.
In GR, the continuous evolution of the rest and moving clock norms into a proper time means that the two clocks can never show interference effects. In other words, the amplitudes and phases of neither matter nor time figure into continuous norms of GR action.
You note that at some small scale as well as some large scale, gravity force dominates over charge force. What QM tells us, though, is that it is exactly at those scales where the GR fails. Relativity's failure to incorporate the amplitude and phase of matter and time means that there are no valid predictions of gravity action at these limits.
Of course, mass-energy equivalence also precludes any QM predictions at these same limits...until matter time comes to the rescue with that new term that stabilizes boson matter inside of the containment of the event horizon torus of an outer matter accretion disk.
In any event, you need some scheme to patch up four critical GR flaws; event horizon, Planck limit, galaxy rotation, and clock interference. The simple expedient of inner to outer momentum transfer due to matter decay seems to take care of the first three of these issues. But the mechanics of GR deal only with the norms of matter and time and so GR is structurally incapable of incorporating clock interference into action.
Only QM allows interference and with interference comes quantization and the evolution of superimposed matter waves. However, it does appear that there is a Schrödinger metric for a proper time amplitude in QM whose norm becomes the proper time norm of GR. That metric now includes the extra momentum transfer term due to matter decay.
What this means is that the GR distortion of space is a valid methodology that incorporates the norms of matter and time for GR deterministic action. However, to predict certain actions it is necessary to incorporate the amplitudes and phases of matter and time, not just the norms. And only QM has the necessary structure to carry the amplitudes and phases of matter and time.
