I don't think anyone's going to fight him 1 on 1. I guess it'd be interesting to see Hashi, Tobirama and Sasuke take on Madara while Minato, Hiruzen and Naruto take on the Juubi. Senju and Uchiha team up while Father, Son and their teacher's teacher teams up. It'd be epic. Taka outside of Sasuke isn't doing anything, I can see Oro with group 2 but I'd find it weird seeing him team up with them.
I think Hashirama will fight him, as Madara doesn't show any interest in the others at all. If Sasuke unlocks Perfect Susanoo, it will be cool to watch him vs Madara though, where I think he will win because of the Enton, which is the strongest nature type i've ever seen.
Hashirama, Tobirama, Naruto, Sasuke, Hiruzen, Gai (8th gate), Lee (maybe 8th gate), Gokage...
These are the ones i want; but i would prefer if the zombie kages were not revieved because it is current generation's time.
