Oooh, you nominated already! \o/ I suspect having, like, Bigfoot/Sasquatch or Nessie/Champ as options would greatly increase the chance of offers, yeah, outside the circle of "hardcore cryptozoology geeks who are also comfortable with rpf". But if what you really want is RPF, go for it! (I have no strong feelings on this one, except the strong feeling that it should be a yuletide fandom at last.)
