Rocky Horror Shadowcast Gang War

Going through some old newspapers and I found this listing of two different movie theaters in the same city both showing THE ROCKY HORROR PICTURE SHOW at the same time. No clue if either one of them had a shadowcast, but it gave me the idea for a short story (or even a series of novels) about a long-running gang war between two different shadowcasts that both operate in an extremely small city. There is only two single-screen theaters in town and both are on the main street near the only traffic light in town. Neither are allowed to burn the other theater down, due to respect to Rocky, so instead they just do silly stuff like messing with each others costumes and cue cards. I can think up thousands of other ideas, but too depressed right now. I'd enjoy seeing an actual voodoo priest involved somehow.
