As long as it's not a serious fight to the death then I'm ok with it. It would be stupid if they ended up fighting like Hashi and Madara did. That would just start the entire story over again. The honestly don't need to fight for Hokage, but if Sasuke believes that power is the way to get people to acknowledge him and want him as Hokage, I would like to see Naruto fight him in order to show him that strength isn't the way to be acknowledged, like Itachi said
