This would be a lot of fun. Maybe a 12 issue monthly with one page or even one panel crossover with every ongoing series. They could even lift a trick from Mad magazine and limit the crossover to the spaces between the panels. We could have infighting between the various Price characters and unlikely groups forming up. Like the Witchfinder General teaming up with the one from the Brady Bunch in Hawaii. The generative event could happen at a Vincent Price festival in Boise, Idaho. It’s a week-long event, and there are films, tapes, books, comic books, cook books, and posters everywhere. Contrived reason to get Superman and Batman there. A bored Mr. Mxyzptlk and Bat-Mite show up for silly reasons and animate all of the Price characters. This would allow the writers to easily choose which ones they want to use. They could play with size based on the images of the characters. So a huge Fredrick Lauren could step out of a movie screen or a tiny one from a comic book. Keep it lighthearted. Go with a silver age vibe for most of it. But go bronze age for anything that would benefit from a serious tone. When it’s done, it could be bundled up in various trade paperback and omnibus editions.
