Seriously, this would be very interesting.
Yeah I think it would. Am I losing it or do I remember the Gracies inviting Judo Gene to take part in UFC at its beginning. Would've been fun to see him in his pink keikogi in the octagon. I think he declined saying: "You nuts, I'm an old man. I'm not stupid enough to get into a ring with you guys." I think he also said that if they put their granpa in the ring with him that'd be a fair match. They declined to do so...
At least thats the story I remember, afraid I can't remember whre I heard it from sadly, it was years ago while I still used to watch UFC stuff.
