Perhaps a plot where Naruto's Rinnegan is a result of a curse placed on him by an ancient evil.

He could learn about the origin of the Rinnegan from old scrolls and seek the help of sage-like characters to overcome the curse.

They must embark on a journey to find the source of the curse. Along the way, they discover secrets about the past Hokages and how to better lead the village. Or perhaps a plot where Sasuke, who has been away from the village for a long time, returns and is shocked to see Naruto's new Hokage - like leadership style. He decides to challenge Naruto not in a fight but in a contest of who can better protect and improve the village, leading to a series of events that show their different approaches.
