Consider the following Hokage lineage
Hashirama - Strong, but an idiot at times and his kindness tends to get in the way
Tobirama - The rational one, but sometimes takes his rationale to an extreme, and is slightly racist
Hiruzen - Sarutobi clan dude that comes after
10 bucks the Hokage lineage is more or less gonna end up like the following
Naruto - Strong, but an idiot at times and his kindness tends to get in the way
Sasuke - The rational one, but sometimes takes his rationale to the extreme, and is slightly racist
Konohamaru - Sarutobi clan dude that comes after
Sounds really basic, but it seems rather convenient that Naruto, Sasuke, and Konohamaru share similarities with the previous first 3. It might not happen but I see a strong possibility that this is the order (sorry Kakashi lol if anything you're probably before them like Obito said). Any thoughts?
Tobirama isn't racist lol The Uchihas and Senjus are related for one thing and he said himself that he didn't hate them but put the village safety first. Sasuke isn't racist either

. Also Sasuke is slightly older than Naruto and a Hokage can be Hokage for many years until their old as Hiruzen did so Naruto would pass the Hokage role to the next generation which would be Konohamaru and not Sasuke. Naruto would have to die for someone from his generation to take over since he's not going to step down after a few years, the Hokage shouldn't be changing much since it can mess up the structure (Hokages would focus on different things and do things differently), Jiraiya said this to Tsunade when she said Kakashi and Naruto are both options when she wanted to go with Jiraiya to the Rain village.
Tobirama took over since Hashirama died (unknown how tho) so Naruto would have to die for Sasuke to take over. Also Tobirama wasn't a missing ninja who joined the village enemy, then joined a international criminal organization which made himself a criminal himself. Sasuke wasn't even acknowledged by Shikamaru, Shino, and Kiba who are in his generation so chances are the villagers wouldn't vote for Sasuke to be Hokage unless Sasuke works hard to make amends as Gaara did over the time skip. Fighting in a war you help cause doesn't make up for anything either since many people like Shikaku, Inochi (sp? Ino dad), Ao, Neji, and many others all died.
I see it being Kakashi (33-34), Naruto (17), Konohamaru (12?) since they are from different generations. Also Naruto is suppose to be the one to fulfill the past Hokage's goals in finding peace, protecting the village, and fix the bad things in the village such as the Hyuuga main branch treating the second branch which he vowed to do in part 1.
