Naruto would likely be involved. He has a strong bond with Kakashi and would surely try to rescue him. Sasuke could also be part of the story. Given his relationship with Itachi, it would add an interesting dynamic.
The theme of sacrifice is also prevalent. Given their complex situations, they may be required to sacrifice things for each other or for the greater good. This could be sacrificing their own safety, their reputations, or their relationships with others in the fan - created stories.
Well, one possibility could be that Itachi has some hidden motive related to the Uchiha clan's secrets. He might think Kakashi knows something crucial. So, he kidnaps him to interrogate him in a secret location.
There could be. There are a lot of creative fans out there who come up with all kinds of unique story concepts. However, I'm not sure exactly where you would find it. You could also check Naruto - related forums where fans might discuss and share such fanfics. It might take some time and effort to search for it though.
Another theme could be the challenges they face together. Given their roles in the Naruto universe, they might encounter various threats or obstacles that they have to overcome as a team, which can strengthen their bond in the story.
The theme of redemption also pops up often. Since Itachi has a complex and somewhat dark past, the OC might be a factor in his journey towards redemption. And for Kakashi, the OC could be a new chapter in his life, helping him move on from past traumas or regrets. This makes for a very interesting dynamic in these fanfictions.
A story about them swapping bodies for a while could be really fun. They have to adapt to each other's abilities and lives while trying to figure out how to swap back. This would involve a lot of character exploration as they experience the world from the other's perspective without any adult - themed content. They might also learn new things about each other and grow as characters.
