First of all..I think it's pretty amazing given the resources you had at your disposal to be able to produce this! You should commission out a mini PCB of the game, once you find out how to rip the code etc. why not make a complete kit and sell them. Although I feel like they did this with DKII cabinets but this is a brand new game entirely.
This artwork can definitely be silk screened by vendors i think you should start an interest thread and sell this as a kit. You can possibly have them done by November just in time for the movie. You never know this game might end up being like "Big Bang Bar" is when capcom only made a half dozen cabinets and eventually 200+ replica's were made and that game seems to fetch 18-30k.
