git-bzr might be a good choice for the "magic" part, yes.

The "rearranging the files" is a simple way to "write" the map of
"gnus-file-name <-> emacs-file-name".  Bzr handles file renaming very
well, so if you do the renaming on the Bzr side, I think it'll work OK.
It doesn't handle removals as well (resulting in conflicts when you
merge changes to the removed file), but it shouldn't be too hard to cook
up a script which will resolve those conflicts automatically.

Since this will involve renaming of all files, the support for renaming
will be important.  If Git handles renames as well as Bzr in such
a case, then it doesn't matter where you do the renaming (on the Git or
the Bzr side).
