I'm also working on a (male) student and (male) Gamekeeper!

Is there any way we can take the 'Purebloods only' part out of Viserious? I like the ambition, cleverness, cunning, resourcefulness but it doesn't really need to be tagged as evil, does it? JK Rowling even said that after Voldemort died, Slytherins were no longer as inherently evil and the curse or stigma was broken.
