One possible plot could be that the reborn brother has a different view on the wizarding world's politics. He might try to convince Harry to take a more active role in changing the way things are run. Along the way, they could encounter ancient magic that has been long forgotten. Their relationship would be tested as they face different challenges, like dealing with the Ministry of Magic's interference, and also dealing with their own personal growth. The brother's presence could also change the relationships Harry has with his friends, as they all adjust to this new addition to their group.
In such a fanfiction, the plot could involve the brother having memories of a past life. This would lead to him guiding Harry in ways that Dumbledore or others couldn't. Maybe they'd explore new areas of the wizarding world that were previously unknown, all while trying to keep their relationship a secret from Voldemort and his followers. Their bond could be a key factor in the ultimate battle between good and evil in the wizarding world.
