Perhaps it could be an older and more experienced Naruto. After years of training, he might have become a master of the Kawarimi. He could use this new - found mastery to face stronger enemies and protect his village. Another possibility is that it could be a hidden ninja from a long - lost clan that has always been proficient in the Kawarimi and now emerges as a master in the story.
It could be an original character created by the fanfiction writer. Someone who has dedicated their life to mastering the Kawarimi technique.
Obviously, Naruto would be one of the main characters since it's about him being the master of Kawarimi. There might also be his friends like Sasuke and Sakura. Sasuke could be a rival in terms of jutsu usage, always trying to outdo Naruto or learn from his new skills. Sakura could be there to support Naruto and also benefit from his knowledge of the Kawarimi no Jutsu in their joint missions.
Well, it could be about Naruto being extremely skilled at the Kawarimi no Jutsu. Maybe it shows him using this substitution technique in unique and unexpected ways during battles, outsmarting his opponents every time.
Well, in fanfiction, 'naruto kawarimi master' might explore a new storyline where a previously unknown character is a master of Kawarimi.

It could be an original character. For example, a young ninja who has a natural talent for katana - wielding but comes from a family of non - combatants.

It could be Naruto himself. Imagine Naruto learning the art of forging to create a special weapon that can harness his chakra in a new way. He might do it to become stronger and protect his friends and the village.
It could be an original character created specifically for the fanfiction. This character might be someone who was initially not very good at ninjutsu but discovers a special affinity for the kage bunshin technique and then devotes themselves to mastering it.
I think Sasuke could be a great main character. He already has an affinity for lightning - based attacks. In a fanfiction, he could further develop his Raiton skills and become an even more powerful Raiton master. He could use his new - found skills to seek revenge in a different way or to protect the village in a more unique manner.
