This is pretty easy to do with a custom importer on sys.meta_path.
Getting the details right is a touch fiddly, but it's conceptually

Hmm, I might play with this - a set of PEP 302 importers to completely
customise the import mechanism. The never-completed "phase 2" of the
PEP included a reimplementation of the built in import mechanism as
hooks. Is there any interest in this actually happening? I've been
looking for an interesting coding project for a while (although I
never have any free time...)
