In principle, we have an almost pluggable architecture. See for example
the latter part of the 2nd post in

http://article.gmane.org/gmane.comp.version-control.git/175127

Unless you want to change git itself, you're probably better off storing
your non-gpg signatures in a note (or a self-created signed tag). To
sign the commit rev, you could sign the output of "git cat-file commit
rev" (or of "git rev-parse rev") and store that signature in a note that
commit. To verify, you verify the note against the commit.
