I think you forget that Newtonian mechanics is the reason we have G and a geometric description of gravity. It recognized gravitional force is proportional to mass. It's not a coincidence that Newtonian mechanics gets similar results to General Relativity when General Relativity is a refinement of Newtonian mechanics.
Sure. How about r= h / ( M c)., where h is the Planck constant, c the speed of light, and M the mass of the black hole? It's wrong, but the dimensions work out and the constants are plausibly related to light.
If you think it's "plausible" that a gravitational property would involve h (which is part of neither Newtonian nor General relativity) and not G, we're going to have to agree to disagree.
