Actually, I don't think there is any more appropriate place for this thread, for now, since you are working out a story request, but have not posted a story yet.
I'll allow this thread to be used as a discussion thread for now, within reason, but I might move it later, if I can figure out a more appropriate forum.
But once you have written the story, please post a link to the story once it's posted, and then create a "review reply" thread in the appropriate forum.
