Gaara could be an interesting addition. Since he has his own experiences with being an outcast, he might have a different perspective on Lemon. He could either help Naruto capture Lemon or try to protect Lemon from Naruto depending on the situation. Shikamaru might be involved as well, using his intelligence to come up with plans to capture Lemon. And Ino could use her mind - transfer jutsu to try and communicate with Lemon to make the capture easier.
There could be other characters like Rock Lee. He might be eager to show off his skills and help Naruto capture Lemon. Tenten could also be involved, providing various tools or weapons that could be useful in the capture. Neji, with his Byakugan, could be used to track Lemon's movements. And Hinata might be there too, secretly supporting Naruto and using her gentle fist techniques if necessary.
Sasuke could be involved. He might be initially against Naruto's plan to capture Lemon, thinking it's a waste of time. But later, he realizes the importance and joins Naruto. Sakura could also be there. She might use her medical ninjutsu to help Naruto if he gets injured during the capture process. Kakashi could be a guiding figure, providing Naruto with strategic advice on how to approach Lemon.
