Ok hear me out. Instead of the Marauders all being in Gryffindor, imagine them each in different houses.
Sirius in Slytherin
James in Gryffindor
Remus in Ravenclaw
Peter in Hufflepuff
Imagine the possibilities!! Not only would it completely defeat the stereotypes that go with each house, but there would be more inter-house relations! This group of four boys that each love each other would prove to everyone that anyone from any house can be friends with everyone else!
AHHH!
