Harem brothers, we must fight to at least get both Hinata and Hanabi in the harem. It would be a waste to not get both sisters. Considering that Naruto has a lot of stamina Hinata would be in trouble. Also, Naruto is one of few survivors of his clan. It would be beneficial for him to get a harem. Not only would he revive his clan faster. Think of the beautiful pair of Hyūga sisters.
Bruh ate a chakra fruit and absorbed a karma seal but he still doesn't have a special eye/doujutsu. Bruuuuuuhhhhhh. Even his lame son had a doujutsu. If you want something that is not overused, then make an original doujutsu and give it to him. Like the mystic eyes of death perception, ultimate eye, all seeing eyes of god, or the six eyes (Gojo's six eyes would be the most suitable since it not only helps in micromanaging energy which would basically gives him the perfect chakra control he lacks but also gives him a good visual acuity and matches with his already blue eyes).
The sage of the sixth path marking Sasuke and naruto with his own karma seal would make him a kind of villain, which could add on to Naruto releasing Kaguya and the Juubi from their seal and taking the juubis power with the help of the chakra fruit , and getting info about the otsutsuki from kaguya and him also awakening Rinnegan coz the chakra fruit..
