Well, an entry in the dictionary "sys.modules" is what is returned by
imports, so you could either pre-replace or post-replace a module by
an object which uses the descriptor technique to get to some (but not
necessarily all) of the attributes.  Think of this technique as a
hack to get to a goal, rather than a good technique to use; good for
debugging, not so nice for production work.  If you still don't know
how to do this from this admittedly sketchy description, I'd suggest
you avoid trying it altogether.
