I would like to see Swick (if he has healed up), that would be an awesome WW debut fight for him. I don't see it being Kos, they don't usually use bigger names as "replacement" fighters. What about Marcus Davis? Luke Cummo? I think Karo is on another level than the both of them but they are names that fans know AND it is the year of the upset so no fighter should be counted out in any fight.
