Wizard Blocks would be the closest thing to getting a new P2K done. Playing the one at Gene's gives the impression that it's still a ways away from being a complete machine but with the right effort it could be finished. The bad thing about WB is the legal issues and that could be a stumbling block (no pun intended). I'm not sure if it could be done in kit form as in the playfield and software sold separate, that too I'm sure would have to pass a legal test.
