Here's an interesting question for you guys. I just wanna see what everyone else thinks.

Most everyone knows about how Blood Status is in Harry Potter, my question is, in Crossovers that introduce witches of different kinds (I.e.: Charmed Witches, or Witches of Eileanan), what would their Blood Status be? Would they be Pureblood, due to actually being the definition of witch, half-blood if they have mortal parents, Muggle born in some cases, or (the really boring scenario) in a genre of their own?
Assuming it was any of the first three, how would Lucius Malfoy react to, say, meeting Piper Halliwell?

Artic's thought for the month.
