Why not it's your choice dude
That would be a good story .. and plus it would still involve madara and hashirama because of obito meeting him and allAwesome.
I'd have the main characters just be Naruto and Sasuke if we were to keep to the main story.
If we could do whatever, I'd love a story of Kakashi. Have Yamato, Guy, Obito, Minato, Rin, etc... be main characters up until their death or what have you. His story is amazing.
If we had a different main character in naruto but was still with Sakura & Sasuke who would you prefer it be .... I say Nagoto or Hinata, Would you still even watch naruto ?
