Or maybe, for once, the Uchiha should be the logical ones, and accept that Naruto (during Madara's era it was Hashirama) deserves the position. Sasuke should accept that the best he can get is right hand man, and then try for Seventh. Sasuke does not in any way deserve the position of Sixth Hokage. If he does become Sixth it would be complete bullshit.
Naruto pretty much has the position there waiting to be picked up. Even after Pain, many of the villagers wanted him to become Hokage. Naruto is the embodiment of "the light", as Konan told Obito. He makes you want to believe in him, and that is what every good leader should do.
Naruto has the respect of all five Kage. He's already close friends with Gaara. They've all acknowledged him and are friendly with him.
Furthermore, not only is he the hero of Konoha, he is also pretty much the hero of the world. Every single shinobi in the Shinobi Alliance owes him their lives (with the possible exception of B). After Madara defeated the five Kages, and before the four Hokages arrived, Naruto was, pretty much, the de facto leader of the Shinobi Alliance.
Now, on to Sasuke. Naruto will, no doubt, welcome him back in the village. But Hokage? Even if Naruto were to turn down the post, the Fire Daimyo / Tsunade would nominate someone else (e.g. Kakashi). Even though he's joined the Shinobi Alliance, Sasuke is still an S-Rank international criminal with a huge criminal record. There is no way he could be Hokage, no matter how fitting you think he is. The Council would never appoint him, and the villagers would never vote him in.
Naruto will be the Sixth Hokage. Sasuke MAY become Seventh.
