Great idea.
Not sure if you're doing it as a kit or not, just thought I'd give you a heads up. Molemento Pete has some kits coming out and so does Hunch (Jim Webb) that have bases that fit in and around the MS bases. Check out the link and post #9 where Pete shows a pic of his next kits and their base placements. (I think this is where you're talking about putting the GG base.)

Another link for Jim's current kits: http://www.tylisaari.com/models/gallery/ms/addon/mslayout.JPG
Not quite sure where Jim's next kit will go but I hear it's a doozy!
