I would've wanted a less beat up Zoro vs King (even if that would've been a quick fight) over a Zoro that broke most of his bones from Kaido vs King but I'll still enjoy the fight if it happens. I don't believe in ZKK personally but I think Zoro's done quite a lot and beating King would just be another great accomplishment, especially considering his state.
Though Sanji vs King is also quite likely if King at any point focuses on Momo. Plus Marco at the moment is still facing King and Queen (well King wasn't around when Queen was held down but before that he was there) so we'll see how everything goes and how Oda handles match-ups. I'm fine with any of the 3 facing King honestly.
