Actually, no.
The moon is lumpy and thus doesn't have a uniform gravity field. Objects in low orbits are slightly perturbed and don't take very long to hit the surface.
An object high enough to make the Mascons not matter is also high enough that Earth perturbs its orbit, and again, takes a short time (months, usually) to either get pulled completely out of orbit or hit the surface.
There are no stable orbits around the moon.
