My favourite favooooourite thing ever written about Hogwarts sorting is that it’s not necessarily the traits you have that Sort you, it’s the traits you value! So bearing that in mind I think Harry would be a concrete Slytherin, having been brought up be Norman to value ambition, and MJ… I think you could make a good argument for her ending up in Slytherin as well, having seen ambition as an escape from her terrible childhood. And Gwen, I always felt she was more or less a Ravenclaw in most interpretations of her to be honest!
So yeah, that sounds like a good AU c:
