Beibut Shumenov V Nathan Cleverly light heavyweight unification in the USA?

BBC was reporting today that Shumenov was inviting Clev to fight him in the US. Cleverly doesn't seem to have a profile over there, so apart from the fact that they both have a share of the title, what else does Cleverly have to offer that would justify going to the US to fight? I imagine it would probably be a pay cut for him, and although Shumenov is a Kazakh he's been based over there for a few years, so seems a bit of an invitation that would only benefit one side of this pairing.

Would think Cleverly had a decent chance if he did take it up, but it seems pretty risky to take up that option in my view.
