Yep. I think that as long as it works, even if you have to change a bunch of names, remove starting units, and even combine them into a superfaction, I'd okay it. The problem with a super faction is that it would be huge, and the existing maps might not be big enough (I made custom maps for the tech tree, since the scarab needs a lot of space, and the maps are kinda cool! There's a maze map that is actually very simple, but very confusing to the human players.)
