One great fanfiction could be about Kakashi using his Sharingan to train Naruto in a special jutsu.

One possible reason could be that Kakashi is in a life - threatening situation and realizes that Naruto is the best candidate to inherit his Sharingan.

Also, it could be a way for Kakashi to show his complete trust in Naruto, as the Sharingan is a very precious and powerful gift.
Well, Naruto already has his own powerful abilities like the Nine - Tails chakra. But getting Kakashi's Sharingan could enhance his perception skills.
