Quoted from Kevin_LHeureux:For older Bally Williams games the System era games and WPC-S they could work but would likely need another component as you suggest. I will look for an opportunity to do some research on it when I have a chance.
Interesting timing... 
This "other component" is something that I've been developing for the last few months. I'm ready to do a test 3D print of a set and just have to coordinate with my friend with a 3D printer to get it done. Once that's done, and testing has been performed to my liking, I'll be finalizing the small details and most likely announcing something here on Pinside. It's quite the kit and has the potential to help a ton of people across a nice scope of games.
That's about all I can say for now. I'd rather announce it all at once when things are done and ready to go. I'm quite excited about it and can't wait to finally lift the veil!
