CPR tried something like this a while back. They were going to put together a custom art package using the Dolly pin as a base. You would get new backglass/plastics/playfield as part of the package, the theme selected was Lost Vegas. I don’t think it ever had enough interest in terms of numbers to make it cost feasible, so it never got off the ground for production. That was back when they were still doing screen printing though, with the new processes, the economics may have changed. Either way, I think the way to start would to pick your game, then gauge interest in terms of numbers. There are a few folks that have done one offs. See the Led Zepplin conversion thread for an idea of what that entails.

So the Lost Vegas was to be an entire package that was sold in quantity for anyone who had Dolly that they wanted to retheme and the Led Zep “one off” is the entire package as well, just doing one machine though. The guy doing the Led Zep did commission an artist to do most of it so that could give you a ballpark for the cost. Search the forum for the specific thread where he talks about it.

I believe CPR was charging around $1300 for the retheme package a few years ago?
