There could be. Fanfiction is a vast world where authors can create all kinds of relationships between characters from different series. Naruto and Orihime are from two very different anime series, Naruto and Bleach respectively. By making Naruto Orihime's brother, the author can introduce new plotlines, character interactions, and explore different aspects of both universes in a single story.
Well, it could be really interesting. Naruto's energetic and determined personality combined with Orihime's kind and sometimes shy nature would make for some great character dynamics. Maybe Naruto, as Orihime's brother, would be very protective of her. He could use his ninja skills to keep her safe in the Bleach universe, which is full of Hollows and other dangerous beings.
One great Naruto and Orihime fanfiction is 'The Unlikely Bond'. It weaves an interesting tale where Naruto somehow ends up in the Bleach universe and meets Orihime. Their interactions are really cool as Naruto's positive energy affects Orihime in a new way, and they team up to face some common threats that cross the boundaries of their two worlds.
There might be a fanfiction where Naruto and Orihime meet in a neutral dimension. They start off as strangers but gradually learn about each other's worlds and form a deep friendship. This could lead to them sharing their dreams and helping each other grow as characters, without any romantic implications if that's not the author's intention.

Well, it depends on different fan communities. In some parts of the anime fanbase, it might be really popular as it offers a fresh take on the characters. Naruto and Orihime come from two different and well - loved series, so when they are paired in a married scenario in fanfiction, it can attract those who are looking for unique and unexpected combinations. They can create stories where Naruto's ninja world and Orihime's spiritual powers interact in interesting ways.
Fanfiction often takes characters and gives them new relationships. Regarding Naruto being Anko's brother, it depends on the specific fanfiction. Some authors might see an interesting plot point in making them siblings. For example, they could write a story where Naruto's positive attitude affects Anko in a new way because of their brother - sister bond. Or perhaps they explore how their shared heritage (if fabricated in the fanfic) influences their ninja paths. But it's important to note that this is not the case in the original Naruto anime and manga.
It could be an unknown brother that was kept secret all this time. Maybe he was hidden away by some enemy of the village and trained to be a powerful adversary for Naruto.
Perhaps Naruto's brother could be a long - lost relative from a far - flung part of the ninja world. He could have been separated from Naruto when they were young due to a war or some political intrigue in the ninja clans.
