RPF/SPN AU With twins?

[lifelesslyndsey.livejournal.com]

So, I was reading some rec's and I stumble upon some fic's in which SPN and RPF were crossed over creating twins out of characters and actors. And there was incest. And I kind of liked it.   Is there more of this? I've read Twin-Verse and Whipporwhil, both amazing.

So yeah. I would like more of this twin idea. Not necessarily twincest, but hey thats a super bonus. Any pairings. I do love the Misha Cas idea. help a girl out?
