Perhaps in the time travel, Fem Naruto ends up being mistaken for someone else in Madara's time. This could lead to all sorts of comical and also tense situations as she tries to figure out how to get back while also dealing with Madara and his plans. For example, she could be mistaken for a long - lost relative of a powerful clan, and have to play along to avoid suspicion.
Another plot could be that Madara and Fem Naruto are both sent back in time, but they lose their memories. They then have to figure out who they are while also being drawn to each other in a strange way. As they regain their memories bit by bit, they have to decide whether to continue on the paths they were originally on or make new choices.
Perhaps they travel back to a time when the Sage of Six Paths was alive. Naruto, with his understanding of modern ninja techniques, and Fem Madara, with her ancient Uchiha knowledge, could learn from the Sage. They might gain new powers or insights that they bring back to their own time. This could lead to a whole new level of power and peace in the ninja world.
One interesting plot could be Naruto and fem Sasuke traveling back in time to their childhood days.

A great 'Naruto fem Madara' fanfiction could revolve around fem Madara being a mentor to Naruto.

Well, a cool plot twist might be that Fem Naruto has a secret lineage related to Madara's own clan. Maybe she discovers this and it makes Madara question his long - held beliefs and grudges. Or perhaps in the fanfiction, Fem Naruto is able to use a new form of ninjutsu that is a combination of Uzumaki and Uchiha techniques, which she uses to outwit Madara in a crucial battle. It could also be that Madara's real goal was to actually find a successor like Fem Naruto all along and his actions were just a test to see if she was worthy.
At first, it could be a relationship full of mistrust. Madara is a very guarded person, and Fem Naruto coming from the future might seem like a threat. But as they start to understand each other's motives, they could develop a begrudging respect.
