Another idea is a time - travel plot where they go back to the founding of Konoha and have to ensure certain events happen correctly to preserve the future. Maybe they meet the original Team 7 in the past and learn from them.
Maybe a powerful enemy has a device that can separate Naruto and Kurama's chakra connection. The fanfiction could focus on how they overcome this setback.

In the end, they reunite and defeat the enemy with a new - found understanding of their relationship.

Kakashi could be a great addition. He could act as a mentor figure during their tag - team adventures. His experience and unique jutsu like the Chidori could complement Naruto and Sasuke's skills. For example, in a battle, Kakashi could use his Sharingan to analyze the enemy's moves while Naruto and Sasuke execute their attacks.
