If the roles were reversed, Sasuke would be the one that Hinata might have a secret crush on. Since he would be the more outgoing and friendly one. And Sasuke would probably be more involved with the village kids, mentoring them like Naruto did. Naruto, as Sasuke, would have a more strained relationship with the Hokage. The Hokage might be constantly worried about Naruto's motives and actions. His relationship with Jiraiya would also change. Jiraiya might be more cautious around Naruto, instead of the carefree mentorship they had in the original story.
In this reversed situation, Sasuke would be the center of the village's hope, and people like Shikamaru would view him differently. Shikamaru might see Sasuke as an inspiration rather than just a peer. Naruto, on the other hand, would have a very different relationship with Orochimaru. Instead of being a threat to Naruto, Orochimaru might see Naruto as a potential ally or tool in his schemes. Sasuke would also have a new relationship with the Akatsuki. They might view him as a nuisance or a target to corrupt, just as they did with Naruto in the original. And Naruto's relationship with Tsunade would be more of a power struggle, as he would be more self - centered in this role and Tsunade would have to keep him in line.
The relationship between Sasuke and Naruto (now from Suna) would be different. Sasuke might view Naruto as more of a threat due to his Jinchuriki status. Gaara, in the Leaf Village, would probably be more friendly towards Sasuke, trying to be his friend. Also, the relationship between Naruto and Sakura would be altered. Since Naruto is from Suna, Sakura might be more hesitant or even fearful of him at first.
The relationship would be very different. Instead of Naruto chasing after Sasuke to bring him back, it might be Sasuke trying to reach out to Naruto. Sasuke would be the more empathetic one, constantly trying to break through Naruto's cold exterior.
Sakura's relationship with the new 'Naruto' (Gaara) would be very different. She might be more cautious around him at first due to Gaara's past reputation. For Kakashi, he'd have to approach mentoring Gaara - as - Naruto in a different way. In Suna, Temari and Kankuro would have to get used to Naruto as their leader. They might be initially skeptical but Naruto's charisma would likely win them over.
Well, their relationship with Kakashi would be different. Instead of just being their teacher, he might see them more as a family unit. He would have to deal with their sibling dynamics, like Naruto and Sasuke's competitiveness and Sakura trying to keep the peace between them.
Sasuke, in the reversed role, would develop in terms of his ability to forgive and his patience. He would have to be patient with Naruto's slow progress towards redemption. His character would become more about spreading hope and love in the face of Naruto's negativity. Naruto's development would be a long and arduous process. He would first resist Sasuke's attempts to change him, but as time goes on, he would start to see the error of his ways. His development would be marked by his struggle between his dark past and the new light that Sasuke is trying to show him.
Well, with Kakashi, he might be more cautious in how he trains Sasuke. As a girl, Kakashi might have to consider different aspects of training, like physical limitations that might come with the female form. His relationship with his clan members, if they were still around, could also be different. They might have different expectations of a female Sasuke. And when it comes to the other male ninja in the village, some might be attracted to him, which would create some awkward or interesting situations.
One possible plot could be that Sasuke, in the reversed role, is now the one trying to gain the village's recognition. He might be the underdog with a big dream, like Naruto originally was. He could be using his Sharingan in new ways to protect the village and its people, while Naruto, in Sasuke's role, has a more brooding and solitary nature, perhaps having left the village due to some past event and Sasuke is now on a journey to bring him back.
In terms of their relationship with their families, if they have any remaining family members. Naruto's family, like Jiraiya (if he's still alive in this fanfiction) could be overjoyed and offer all kinds of support. Sasuke's family, perhaps Itachi (again, if alive) might have a more complex reaction, being both proud and worried about the future of the Uchiha bloodline with this new development.
First of all, Naruto and Sasuke's relationship would take a hit. They have this intense connection in the original story, and this sudden act by Naruto would make Sasuke feel like Naruto has abandoned their relationship. For Ino, she would be thrown into a new situation. She may have had her eyes on Sasuke before, but now Naruto has kissed her. This could make her reevaluate her feelings for both of them. As for the other characters, they would be shocked. Shikamaru might be especially intrigued as he's a close friend of Ino. He would probably try to figure out what's going on in Naruto and Ino's heads, and this could also create new interactions and relationships among the group.
Well, their relationships would definitely change for the better. Naruto would look at Sasuke more as a brother, and Sasuke would be more open to Naruto's friendship. Since Kakashi is there to guide them, he would encourage them to communicate their feelings more openly. Sakura would no longer feel left out. She would be an equal part of their little family. They would start to rely on each other more in different aspects. In battles, they would have a deeper trust. Naruto might trust Sasuke's judgment more, and Sasuke would trust Naruto's instinct. And Sakura would be more confident in their support, which would in turn make her a stronger fighter and a better friend.
