It's not a very common or mainstream fanfiction concept. 'Naruto' and 'Beast Boy' are from different fictional universes ('Naruto' from its own ninja - themed world and 'Beast Boy' from the Teen Titans universe). Combining them in such a way might be a very niche and creative idea that only a small number of fans might explore in fanfiction.
One possible plotline could be that the boy in the war is a hidden shinobi from a small village. He might have unique abilities that are crucial for the outcome of the war. For example, he could possess a rare bloodline limit that the enemy is trying to either control or eliminate. And Naruto, being the protagonist, might cross paths with him and try to protect him from the horrors of war while also learning something from his experiences.
One possible plotline could be Naruto growing up with Kakashi's unique training methods. Since Kakashi is known for his strict and strategic training, Naruto might become an even more formidable ninja at a younger age. He could inherit Kakashi's Sharingan abilities in some creative way in this fanfiction world, which would give him a whole new set of skills to master.
A possible plotline is that Kisame left behind a child (Naruto) before his death. Naruto is then raised in Konoha, but he has strange dreams and instincts that he doesn't understand. As he gets stronger, he starts to show abilities that are not typical of Konoha - style ninja. When he finds out about Kisame being his father, he decides to explore the Akatsuki's side of the story. He could try to understand why his father was part of such a group. Along the way, he might meet characters who knew Kisame and learn more about his father's past, which in turn helps him understand his own place in the ninja world.
One possible plotline could be Naruto having an innate understanding of the Wood Style jutsu due to his relation to Hashirama. He might discover this connection early on and struggle with the implications. Another could be that the village treats him differently, with some seeing him as a symbol of the Senju legacy, while others might fear his potential power.

Well, a plot could involve Naruto facing challenges related to his new identity as a Senju. There could be those who oppose him having the Senju blood, perhaps out of jealousy or fear of his growing power. He might have to prove himself worthy of the Senju name. Also, his friendship with Sasuke could take on a new dimension. Since Sasuke is an Uchiha, there could be an interesting dynamic between the two clans' legacies within their friendship. Naruto could use his Senju powers to try and bridge the gap between the Uchiha and the rest of the village, as the Senju were often associated with peace - building in the past.
