Harry Potter and Queer as Folk

I'm reading Harry Potter Gives a Shit by Talithan and while I'm enjoying it, it's the second re-write of Queer as Folk I've read in which Harry is cast as Brian Kinney (this one has Draco as Justin, the other had Draco as Mikey). WTF? I don't mean that a pejorative - I just honestly don't understand it!

Does this make sense to anyone else? And does anyone know of any re-writes that cast Draco as Brian? Because that's a much more natural casting than Harry-as-Brian, to me. If I can't find it, I might have to write it myself!
