Could General Relativity be directly connected to Quantum Mechanics through Newtonian Mechanics as an emergant middle point?

Question: Is General Relativity as much an emergent behaviour of Newtonian Mechanics, as much as Newtonian Mechanics is an emergent behaviour of Quantum Mechanics?

Thus, the elusive Theory of Everything may be defined by inversing our focus from measuring the micro using the macro, and instead utilizing derivation of the emergant behaviour contrasted between the micro and macro.

I know many more focused and smarter people had pondered upon this. Hence, I invoke the sacred rights of being wrong in the interwebs. Hit me with your best debate.

newtonian mechanics is just an approximation of behavior more accurately described by relativistic mechanics. We tend to still use it because the math is easier and the error is usually lower than we care about at low speeds/grav fields. Relativistic mechanics are just a more accurate model of the universe. They aren't emerging from classical mechanics. The newtonian model is just wrong for lack of a better word. Still a useful simplification tho, but i don't see how relativity could be an emergent behavior of it. It feels like saying π emerges from the fractions 22/7 instead of the ratio between a circle's circumference and diameter.

Thus, the elusive Theory of Everything may be defined by inversing our focus from measuring the micro using the macro, and instead utilizing derivation of the emergant behaviour contrasted between the micro and macro.

what does this word salad even mean? like what are you actually suggesting? Newtonian mechanics isn't helpful for solving problems on relativistic or quantum scales and im not seeing how it provides any useful bridge to solve quantum-gravitational problems either.

tbh I'm not really understanding what you're trying to say... But if solving the Theory Of Everything was as easing as combing Quantum Peanut Butter and Newtonian Jelly I'm sure scientists would've tried that already.

Newtonian mechanics are convenient approximations of general relativity at non-relativistic speeds. General relativity is not an “emergent behavior” of Newtonian mechanics. Nor is Newtonian mechanics an emergent behavior of Q.M. I’m not sure where you got the idea that it was, but it’s sufficient to say that your idea is not a means of achieving a ToE.

If you take the theory of everything, and make some simplifying approximations, you should get general relativity. Different simplifying approximations should get you quantum mechanics.

The simplifying approximations that turn general relativity/quantum mechanics into Newtonian mechanics are pretty well understood. (Though also often misunderstood, especially with quantum mechanics)
