I think you won't get away with using --subdirectory-filter. You'll have to
do the inverse: filter-branch and remove everything outside the
subdirectory that you don't want to keep, and then move the contents of the
subdirectory to the root of the repository.
You could also try out the more recent git subtree
see if that does what you need automatically (although I doubt it).
