I mean, Pein should have little trouble dealing with Kakuzu and Hidan. And I can't see the pair having anything to go through Madara's body-phasing, although if Hidan got some blood, that would do the trick. I don't think he can, though, even with Kakuzu's help - not against Madara.

Anyway, Nikushimi, the outcome of a match-up between Itachi and Madara is nowhere near certain, so you can't use that as an argument.
