Senor, your analogy seems fine on the qualitative level, but the problem that beguiles physics right now is there is no formal way to put the metric of gravity together with quantum action unless you end up with ridiculously high vacuum energy densities (that are off observationally by factors of 10^60 at best). Your unification idea is one that has been tried often, but as of yet there's no good way to put it together mathematically.
