I think the possibility has been mentioned by Kovalev. I'd imagine he'd do pretty well - he might not carry all his power up but clearly the guy can box just fine.
Hmm, he can beat those 2 british buffoons cleverley and bellend. He would get out manned by Lebedev and Huck. He has chance vs Ovil McKenzie, dodgey chin but hits quite hard. He would have a chance vs arslan as hes a plodder, and he isnt hard to miss. Hernandez would probably be too big and outbox him, kovalev punching chance. Diablo would be too hard hitting and tough, despite his limitations. I dont know too much about drozd or mchunu. so it will be tough for him.
I give Kovalev a good chance at beating any of those paper champs at CW. I wonder if any of those wusses will ever man up and try to unify a belt
