Kakashi could also be a potential assassin master. With his Sharingan and his own brand of stealth and combat skills, he could teach Naruto how to be more deadly in combat and how to move undetected. He has already trained Naruto to some extent, so it would be a natural progression.
Jiraiya could be an interesting assassin master. He already has a lot of knowledge and skills that he could pass on to Naruto in a more assassin - like way. His experience in espionage and combat would make him a great fit.
It could be a former Auror who has turned to more shadowy ways of dealing with threats. After seeing the inefficiency of the Ministry's methods in some cases, they decide to take matters into their own hands and become a sort of assassin to target dark wizards.
Perhaps a foreign ninja who comes to the Hidden Leaf Village. They bring with them the scythe - using techniques from their own land. This ninja could be on a mission to learn more about the chakra system in the Naruto world and in exchange, teach their scythe skills. Their different cultural background would add an interesting dynamic to the story as they interact with the local ninjas.

One main theme is often power and its acquisition. Naruto, as an assassin, is constantly seeking to gain more power to achieve his goals, whether it's protecting his village or avenging someone. Another theme is secrecy. Since assassins operate in the shadows, there's a lot about hiding identities and motives.
It could be a rogue ninja who was once a student of the Hiraishin master but turned evil. They might have a twisted view of the technique and use it for their own selfish and harmful purposes, like stealing important artifacts from different villages.
One potential antagonist could be a rogue ninja who also specializes in bojutsu. He might be jealous of the main character's skills and tries to undermine him at every turn. Another option is a powerful villain from the Naruto universe who sees the bojutsu master as a threat to his plans.
A new character could be introduced as a Sharingan master. For example, a wandering ninja who has been secretly studying the Sharingan for years. He might have no allegiance to any village and travels around, looking for worthy pupils to inherit his knowledge. He could have unique techniques related to the Sharingan that no one has seen before.
It could be a rogue ninja from a village that specializes in earth - style jutsus. Since futon techniques are weak against earth - style, this enemy would pose a significant threat to the Futon Master. They might target the Futon Master to steal their techniques or to prove the superiority of earth - style over futon - style.
Sasuke could be a rival. He's always been highly skilled and competitive. His Sharingan could potentially see through some of the henge master's henges, creating a constant challenge for the henge master to come up with more advanced henges.
