Current Choji is apparently able to take out Kakuzu (which I find laughable, how can being a large target help AT ALL against a large-scale ninjutsu specialist) maybe he could make a difference?
Ah, who am I kidding. I'd put my money on the whole of Akatsuki vs any single Hidden Village, the Konoha 11 posing a challenge is just idiotic.
EDIT: People seem to be forgetting that Kisame could feasibly solo too.
(As could Sasori with either Third Kazekage or 1000 puppets, Deidara with C3, C4 or C0, though C4 could be avoided with the Byakugan, Kakuzu with combination elemental attacks 'till they're carbonized, Konan if she has her bombs prepped... Hell, even Zetsu could if he can outlast them with many many many clones)
The only member of Akatsuki who COULDN'T win this battle ALONE would be Hidan
