The 2019 Spooky Town has some discussion on the thread "Collecting to Create Halloween Displays - Not Just the Boney Bunch ". I talked about the 2019 collection and its availability. Check out that thread. I believe the post is dated 3/30/19.
I would love a Bonecula re-issue. Good question. I wonder if Mark designed any or all of those protorypes. They were great pieces. Too bad they thought that they weren't good enough to be a part of the Boney Bunch.
