Well, I propose Lupin for the role of the black guy, and Tonks for the role of the guy from Brooklyn. Lupin was the token outsider, fighting the good fight for a society he wasn't really comfortable in, and Tonks' accent ("Wotcher, Harry!") can stand in as the British equivalent of Brooklynese.
I have no idea who took the role of the blind French girl, though. Fleur survived, and I don't know who else would fit... unless I'm just stretching the metaphor too far! :-P
