Yes, it is an option when the camera is static and changes are only of
the geometry in front. But I guess you will get clear discontinuities
in the edges of the renders. And still has the problem of ghosts.

My interpolation with difference matting approach has problems with
shadows too, things get a bit blured there, but I think it could be
partially fixed by smarter matting.
