Just thought of something else...I say straddle the show. Part of what made the show work in the 70s was that it was a game show that let the game take a backseat to the hijinks. I'm not saying it needs to take the form of a sitcom, but find that perfect balance of fun and games*. With returning champs, just do one Super Match, $250-500-1000, and maybe a Star Wheel, but no biggie if not.
*In other words, watch any eps. made between 1974 and '77
