Dana has already stated he's not looking to mix MMA & Boxing again. I think if they bring MMA guys over to boxing you potentially hurt the UFC brand anyway & lets not act like guys aren't getting injured & falling out of fight dates all the time. That would be a huger problem if they let some of their biggest fighters switch over to boxing.
I wouldn't be shocked if they switched Cyborg over to boxing from time to time. The UFC doesn't even have any fighters in Cyborg's weight division as we speak so it might actually make sense for them to let Cyborg box + she's saying she'd love to box. She brought in Cecilia Brækhus & Claressa Shields to spar her for this Holly Holm camp. So that could happen even with Dana signing legit boxers to "Zuffa Boxing" or whatever this entity gets called.
