A possible plotline could also be about the relationships Harry forms. He would have a closer bond with the Marauders, and this would change his dynamics with other characters. For instance, his relationship with Snape might be even more tense as the Marauders had their own history with Snape, and Harry would be more likely to side with his guardians in any disputes.
