One great plot twist could be that Itachi was actually working undercover all along to protect Naruto, not just for the sake of the village.

Writers often develop Naruto's character by emphasizing his growth in understanding Itachi. At first, Naruto might be full of anger towards Itachi because of what he did to Sasuke.

He has to balance his loyalty to the village with his love for his brother.
One possible plot twist could be that Naruto, after learning more about Itachi's sacrifices for the village, starts to idolize him in a way that changes his own ninja path. He might adopt some of Itachi's stealthy and strategic techniques. For example, he could focus more on gathering intelligence before acting, rather than his usual head - on approach.

One interesting plot twist could be that since they are the same age, they become rivals not just in power but also in terms of winning the affection of their peers.

Another could be that they end up in the same ninja team, which is unheard of in the original story. This would force them to work together and learn from each other's strengths, like Naruto teaching Itachi about the power of friendship and Itachi teaching Naruto more refined ninjutsu techniques.

Kakashi, who had a certain view of Itachi, would now be dealing with a Naruto - influenced Itachi.
