We would need global symbol macros.  But even these would not be able to
affect variable references from C I think.

Symbol macros are also a bit fragile in Elisp, and some completely
dislike them (Richard for example).

So, yes, this is suggesting itself but would make the problem to solve
even harder, unfortunately.
