As of now Naruto and Sasuke would probably be the ultimate team up, I mean with Bijuu and Sharingan they probably could take down the current Gokages in a five on two battle. The future generation starts with them, hopefully the other Konoha kids can catch up in the distant future. This war could have been the stomping grounds for the young folks to make names for themselves and so far only Shikamaru, Choji, and Ino have done anything on panel from the Konoha eleven kids. Neji, Tenten, Hinata, Kiba, Shino, and Lee have been fighting mostly off panel and Sakura has been stuck in her lame stereotype female nurse job.
As far as Madara goes, he is so broken that I actually would be somewhat disappointed if the Gokage actually do manage to defeat or seal him. Because so far none of them have shown to be anywhere near as good as this uber hax and for them to magically beat him when they can barely touch him would be insanely forced. Just have him disappear with the Edo Tensei's. Madara Uchiha...the real reason the elders wanted the Uchiha's dead.
Pokemon Left version and Pokemon Right version. They are coming soon.
