Fat chance on your wait lists unless someone gives up a partial concierge reservation because they just don't want to move to different rooms while there.
I called at the very first moment that concierge could be booked back in June of last year and by 9:08 am EST I was waitlisted for Dec 1 concierge studio at AKV. I never got it. Even worse, on the
DCL cruise Dec 2-6, the
DVC representative there told us he'd stayed concierge at AKV the night before the cruise (MY night, Dec 1) because MS told him to call the lodge directly to see if he could get in at the last minute.

Yes, I was really really irritated when he told me that on the cruise. I still am. I doubt MS wants us to start calling the DVC villas directly to try to get the rooms we want at the last minute but it really isn't fair that I called in June and couldn't get the room that the DVC guide got at the last second.
