I would volunteer to participate, but alas, I think it wiser for me to remain an observer. Although I have role-played quite extensively, I've never done so online, and I am not familiar with the protocols (and such). Perhaps if I observe long enough, I will get the hang of it, and can join the merry band at some later point. There are always new characters popping into bad fanfic at much too convenient moments.
That said, I might suggest that Bree is a logical starting point. I think the more relaxed atmosphere of Bree would be an easier spot for the intrepid Sues to surreptitiously get wind of the Real Quest, so that they can get their own misguided notions, let them grow into certainty en route to Rivendell, and then present them to someone like Elrond ("But the Company has already left, my daught-- wait a second, you're not my daughter! Who the...???")
