Yeah, I'd agree that Merlin fandom is easygoing about pairings - anything involving Uther or especially Gaius might squick some, but it seems pretty unlikely that someone would've written say only Uther non-con fic and sign up to be remixed.

I have basically no insight in Merlin RPF, but I hope you get it to work. Especially if we get a lot of writing time in August this Merlin remix would work so much better for me than RemixRedux. Exciting!
