i think NaruSasu would be great if Sasuke was a girl

I actually think that might be true. The tension between those two already cause people to make gay jokes about them despite it being obvious that Naruto likes girls and Sasuke just being neutral to anything sexual.
Also, I don't think it's that common that there's a story with a male hero and a female rival, so that would've also been innovative.
I think most commonly it's a hero and rival who are both male or female, or (I think mostly in Shoujo) a female hero and male rival. So having a story being told from the perspective of a guy that wants to be acknowledged by a girl in terms of both power and love is something I would like to see.
