A really interesting plot twist could be that Naruto travels to a time during the Fourth Great Ninja War, but with his 7th Hokage powers. He could potentially end the war much more quickly and with fewer casualties. This would change the post - war world in ways we can't even imagine. For instance, the villages might not be as damaged, and there would be less hatred and distrust between the different ninja clans.
Maybe Naruto travels back to his own childhood days. He could use his knowledge as Hokage to help his younger self become stronger faster. He might also be able to prevent some of the hardships he faced, like not having enough food sometimes. This would not only change his own life but also the relationships he had with people like Iruka - sensei, who took him under his wing when he was a lonely kid.
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.
One possible plot twist could be that Naruto has to face unexpected opposition from within the village. Some of the elders might not be fully on board with him becoming the 5th Hokage because of his unorthodox ways. They could try to set up various challenges and tests for him to prove his worthiness. Another twist could be that an old enemy resurfaces, specifically targeting Naruto because of his new position as Hokage. This enemy might have some vendetta against the village leadership and sees Naruto as an easy target to strike at the heart of Konoha.
A common plot twist in Naruto Rokudaime Hokage time travel fanfiction is that the time - traveling Hokage accidentally alters the fate of a major character. This could be someone like Naruto himself or Sasuke. By changing their past, the future of the ninja world is thrown into chaos. For example, if he prevents Naruto from getting a certain power - up in the past, it could mean that the ninja villages are not as united in the present. Or perhaps the Rokudaime Hokage's time travel causes a shift in the balance of power between the different ninja clans. This then leads to new rivalries and alliances that were not present in the original timeline.
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.
One possible plot could be Naruto dealing with the post - war reconstruction. He might focus on rebuilding the village, strengthening relations with other villages, and also mentoring the new generation of ninjas. For example, he could start new training programs inspired by his own experiences.
One possible plot twist could be that Sadime Hokage is secretly from an enemy village but has been undercover in Konoha for years. She falls in love with Naruto during her time there and has to choose between her loyalty to her original village and her newfound feelings. Another could be that Naruto discovers a hidden power within Sadime that is related to an ancient prophecy, and they must work together to prevent a great disaster.
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 fanfic might focus on the 6th Hokage's personal growth. He could start off with insecurities but as the story progresses, he overcomes them through various trials. For example, he might have to deal with a powerful rogue ninja who challenges his authority. In the process, he discovers new powers within himself and also learns more about the history of the ninja world. This growth not only makes him a better leader but also a more respected figure among the ninja community.
One possible plot twist could be that Naruto and Tayuya travel back to a time when the Hidden Leaf Village was first founded. This would put them in the middle of the early power struggles and they might have to use their future knowledge to prevent a great disaster.

One possible plot twist could be that their time travel messes up the existing timeline in ways they didn't expect. For example, they might accidentally prevent important events from happening in the past that were crucial for the future they came from. Another could be that they find out they were meant to time travel all along to fix a long - hidden problem in the ninja world's history.
