Git: move files in history too

is it possible with Git's tools to move files into a new folder while modifying its full history, as if the files had been there from their first add?

I came up on this after merging some repos together: I moved the files from several repos to distinct folders inside one "super" repo, however the merged history behaves very bad with git rebase and git svn tools as totally different files may collide at their old locations of course.
