If Calzaghe is willing to come back for 10m, how likely is this?

So if he is wiling to comeback for 10m, how likely would it be that he'll fight the Super Six winner? After all the promotion of the tournament, etc. there's going to be a huge amount of money around the winner. Would it be possible that sort of money could be offered to Calzaghe? If it's Kessler who wins then that's more of a been there done that sort of thing, so I don't think it would happen then. But if Froch wins (don't laugh) then that would be a natural fight, what with all the trash talk he's given. Or the clash of styles if someone like Abraham wins. I think that would produce a very memorable fight. How likely is this?
