For Erica, I'm down for just about anything. I'll ship her with almost anyone (at the very least smut her with just about anyone). Love Erica/Stiles & Erica/Isaac. I'll play her canon or AU. I've got a version of her that was attacked by Peter at the formal instead of Lydia. Wouldn't mind playing her AU from the last couple episodes, too.
I've also got a Kate Argent journal around. I'd love one of the Hale boys for shippy &/or smutting purposes. All her lines are going to be very very dark. I'd much rather play her some version of AU than strictly canon (mostly cuz she's dead and kind of one dimensional). I've got a couple ideas where she didn't die when Peter attacked her, one of which is her being turned instead. I'd love to explore the whys of her burning down the Hale house (and have some ideas on how to involve Peter in that story). I just want to play Kate!!
