There could be. Fanfiction often takes creative liberties with the original story. However, this particular concept might be a bit of a stretch considering their original relationship in the Naruto series.

Yes, there are some fanfics out there with this concept. It's an interesting take on the Naruto universe as it completely changes the dynamics between the two characters. They would have a very different relationship compared to the original series, with Naruto being more of a protective family figure to Sakura.
One possible plot could be that they discover they are siblings later in life. Maybe there was some sort of hidden family secret or a mix - up at birth. Then they would have to deal with the emotional turmoil of this new revelation while still being part of the ninja world. They might also have to face the reactions of their friends like Sasuke, who would have to adjust to this new family dynamic.

Sakura might have taught Naruto some of her book smarts when it comes to ninjutsu theory, and Naruto could have shown Sakura some of his more unorthodox but effective combat techniques.
