I was gonna jump in the other thread, but I spotted it too late yesterday. Hope it's okay I jump in here.

I'm not really familiar with Charmed or how a demon alchemist works, but if you need a less demonic alchemist, I'd be willing to throw Al into the play. He'd probably be hesitant to try to do something like change blood, but Angel isn't exactly human, so the results might be a little different. *shrug* If it works out for you guys, that is. Either way is fine by me.
