Hmm... It might be possible, but probably not worth the effort. You can play with the superbubble script and see if you can make a cab out of the package(s). I wouldn't hold my breath about it though... It's likely they had to modify many existing services to change things around for the start menu. Plus there is likely some coding involved in the manipulation of the tiles on the start menu. I'd say just stick with the existing mods that replicate the win7 functionality.
