The other stuff doesn't, really.
It wouldn't take too much of a difference in Harry's history to make him not want quite so strongly to be put into Gryffindor. All you'd need to do is tweak his family history so that he has someone other than the Dursleys that he considers "family", so that his parents fade into his past rather than being preserved in his mind as the only people who really loved him. Having a twin might change things to the point that Harry would care more about his living brother than about his long-dead parents, and not care so much about being in the same House as his folks.
But... well, heart-shaped scars? Taking Harry's place? Sorry, but no. That's blatant Stu. If you wanna do a decent AU fic about Harry having a twin, you should be focusing on Harry, not wedging your OC into the story sideways.
