A really cool plot would be if Kurama was actually a key to a parallel ninja world. As they become friends, Naruto and Kurama accidentally open a portal to this world. In this new world, they find different versions of their friends and enemies. They have to work together to find a way back home while also dealing with the chaos in this parallel world. It would be full of new adventures and challenges for them.
One interesting plot could be that Kurama has a hidden past related to the creation of the ninja world. As Naruto and Kurama become friends, Kurama reveals this past. It could involve ancient ninja clans and forgotten jutsus. Naruto then uses this knowledge, along with Kurama's power, to bring about a new era of peace in the ninja world.
Maybe a plot where Kurama gets sick. Since he's a tailed beast, this is a very strange situation. Naruto, as his friend, has to find a way to cure him. He travels to different parts of the ninja world, meets new characters, and discovers new forms of medical ninjutsu. Along the way, their friendship deepens as Naruto shows his determination to save Kurama no matter what.
