I think a two co-hokage system should be used. Naruto obviously has enough power, and Kakashi has superior intellect and experience with quite a bit of fighting capability to boot. Kakashi is too weak to be hokage, and Naruto is just too dumb and inexperienced. Therefore, the two complement each other flawlessly.
ALso, Sasuke I don't think cares to come back to Konoha. I think it is really wierd how he made this Team Hebi, but Hebi is never seen in battle with Sasuke. I dunno, I just think perhaps Sasuke will roam around with this "team" of his.
