I'd like to see more of Hashirama and Tobirama. What happened after VoTE, how did they die. Did Kakuzu kill an old rusty Hashirama? xD
Then Hiruzen's ascension to Hokage, the Sannin's story, etc.
Basically from the So6P's death up till kid Naruto on the swing =D
And after like 1-2 years make something futuristic, a time skip like Naruto Hokage, Sasuke kage of his own village and from there on is Kishi's imagination
Altough Naruto is supposed to bring peace to the world, so if there will still be war with Naruto as hokage it would be bad writing imo lol
