If there were a Fletcherbird, perhaps he could come with an At the Dance playset? After all, he was a dancer and the larger characters are going to have to be worked into playsets.
But anyway, I seriously doubt that either Fletcher or the Bossmen will be made- too obscure, even by fan standards. There's also the issue of the performer of Fletcherbird, Graham Fletcher- I would think they'd need to get his permission too.
