Might be wishful thinking. The energy levels where a unifying theory might pop out seem to be out of reach right now. Doesn't seem that we're just missing something that's already in our data.
As a historical precedent consider Newtonian vs. Einsteinian mechanics. Newtonian mechanics works fine at familiar scales of time, space, force, power, mass, etc. Einsteinian mechanics also works fine at those scales. If that's all the data you have, they are equivalent theories. Yet Einsteinian mechanics also predicts things far beyond that scale correctly while Newtonian mechanics does not.
I still think it's an interesting thing to attempt and may suggest new experimental predictions. What if an alternative model makes a novel prediction that is testable?
