One possible plot could be that fem Naruto travels back in time to her younger self. She uses her knowledge as a Hokage to prevent certain tragedies. For example, she could stop Sasuke from leaving the village in the first place. This would change the whole course of events in the Naruto world.
Her relationship with Sasuke would be very different. If she time - travels back, she might be able to approach Sasuke in a more mature way as a Hokage. Instead of just chasing after him out of friendship and rivalry, she could offer him real solutions to his problems and help him find his place in the village without leaving.
One great 'Naruto Hokage Time Travel Fanfiction' is 'A New Beginning'. It has an interesting plot where Naruto travels back in time and uses his knowledge to change many things in the ninja world. The character development is really well - done, especially how Naruto becomes more cautious and strategic with his second chance at life.
Another possibility is Naruto traveling back to his own childhood days. He could mentor his younger self, teaching him advanced jutsu and wisdom he's gained over the years. This would make his younger self much stronger much earlier, and might also change how he interacts with Sasuke. For example, he could help his younger self better understand Sasuke's pain and prevent some of their earlier conflicts.
Another idea for this fanfiction is that Naruto's time travel as the 6th Hokage could lead to him meeting his predecessors in a different way. He could learn new jutsu or leadership skills directly from them. For instance, he could have in - depth conversations with the 1st Hokage, Hashirama, about how to better manage the relationships between different ninja clans and build a stronger, more united village.
The idea of time travel in 'Naruto Hokage Time Travel Fanfiction' is appealing because it allows for a lot of 'what - if' scenarios. Fans can see how Naruto, as a Hokage, would change things if given a second chance. It's a chance to rewrite the story in a more ideal way.
If Naruto changes something major in the past, it could disrupt the timeline. For example, if he prevents the Uchiha massacre, Sasuke's path would be completely different. He might not have the same drive for revenge, which could mean he doesn't leave Konoha. This would change Naruto's own growth as a ninja, as Sasuke was a big part of his motivation to get stronger.
Well, Naruto could go back in time and train his younger self. He'd be able to pass on all the skills and knowledge he has as the 6th Hokage. This would make his younger self much stronger and more confident much earlier in life.
