A possible storyline is that Naruto accidentally stumbles upon a hidden dojo where Rokushiki is practiced. The dojo master, seeing Naruto's potential, takes him in as a student. As he learns Rokushiki, he has to face the challenges of combining it with his ninja skills. He might also face opposition from some of the other students who are jealous of his natural talent. This could lead to various conflicts and growth for Naruto's character within the fanfic.
Yes, there might be. Some fanfics like to give Naruto new abilities and having him quickly master Rokushiki could be an interesting plot point. Writers often enjoy exploring how a character from one universe would adapt to skills from another.
