The conditions in the very early history of the Universe (<10^-43 sec after the BB) would seem to support a single unified force.
I'm not sure whether you're advocating local causality by the implication that the state of a particle in space-time are supplied through a global reference frame.
An obvious question that comes to mind is how do you explain quantum entanglement or better still the status of Bell's theorem (is the inequality violated or not).
For example there are tests with photon pairs (entangled pairs) where if the photons are "separated", the state of a given photon is determined by the state of the other photon. This has been experimentally determined by polarization tests.
This would seem to run counter to what you are advocating.

It's a nice enough idea, but Grand Unification (QCD-electroweak interactions) will need to be seen. I don't think anybody's come up with a neat Quantum Gravity as yet. What's the closest so far, 'M-theory' ?
And I think both of these suggestions require S-Symmetry in order to predict an energy level for convergence.
"how do you explain quantum entanglement or better...Bell's inequality"
In the mail.
"This would seem to run counter to what you are advocating"
I don't mean to do so; I'm advocating an alternative; a local and non-local system at the same time, without violating SR. Something that also describes the inability for a history vector to come back to the event interaction point through devolution under 'local' law. There's an element missing, a non-local, time asymmetric process which needs (MUST) account for probability and show why freedom of choice is retained (similar to relativity, where a relative viewpoint has affect over spacetime. In this freedom of choice has affect over deterministic processes and can collapse probability). So, it must handle freedom of choice too and GR as I pointed out earlier. Huge call, I know.
I'm not elluding to a 'Relative State' interpretation, nor 'Bohmian Mechanics', or even 'Sum over Paths' postulate (Feynman), but something quite different. I feel you can flip these three ideas up on their heads, and end up with a single mechanism which can determine local events, in full view (so to speak) of a 'whole world' of particle states. Einstein's evolution equations had an aspect of this.
I looked to Aharanov's TSQM (Time Symmetry in Quantum Mechanics) for some background early on.
