Given the recent announcement of a Dr. Strange movie, I wonder if they aren't looking to make that into a pin? Stern has a history of producing games based on superheros, movies and Marvel licenses, and I would think that it fits John Trudeau's description of a fantastical and edgy theme.
I think a Dr. Strange pin with ZY artwork could be extremely cool. If they used an upgraded "ecto goggle" setup, they could even add some trippy astral projection type stuff into the play.
On the other hand, I might have to sell a kidney to buy another game...
