Welcome to Chipped, everyone's favorite cooking game show! Each cooking round is a timed ball, and the better you do, the more rounds you get. At the start of a round, you're given three ingredients, which start out normal and progress to comically bizarre (round 15: all spiders), and you have to hit certain shots to make your dish correctly. As you progress, you watch your dish be cooked and assembled in the in-playfield screen via Cooking Mama-esque animations, but watch out! If you hit the wrong shots, you'll goof up. At the end of the round, your dish is presented to the judges (parodies of people like Alex Guernaschelli), and you have to stay above a certain cumulative judging score to stay in the game. For an easter egg, hit only the shots you're not supposed to and create a lethal dish! Kill all three judges to start dead judge frenzy, which scores negative points and puts you on a separate high score roster.
edit: and how about Willy Wonka? Since the musical is transferring to Broadway, that would open up a lot of options for music and freshly-recorded dialogue. It could be a progressive game - first you have to qualify and collect all five golden tickets. Each golden tickets starts a bonus scoring, e.g. every time you hit a bumper, Augustus eats another chocolate bar and his weight increases (accompanied by an appropriate DMD animation), or every time you flip the spinner Violet gets another brand deal, or every time you circle the mixing funnel Veruca's dad buys her another (increasingly ludicrous) thing, or every time you hit the side standups with the upper flipper Charlie collects another piece of garbage, etc. While doing this, you count down the clock to open the factory, build towards Wonkamania frenzy (which awards more points the closer you are to opening the factory, and becomes a post-drain bonus if you don't collect it before doing so), and collect random awards from the wheel, which is themed as a professor's high-tech gold-finding machine (if unlucky, it strikes out and grabs a gold filling from a passerby, awarding you nothing).
Once the factory gates are open, you enter and play through a chocolate room multiball before moving on to dispatching the kids. Examples: Augustus goes first, naturally, and in this hurry-up mode you build the pressure on the tube to send him up the pipe. Violet's mode is a looping shot, in which you must roll her to the juicing room before she explodes, and functions as an inverse hurry-up - the longer you take to get her there, the higher the payout, unless she explodes, in which case you only get a little bit (for what can be "scooped up"). Mike is a video mode (duh).
Also in the factory are glass elevator modes, which take you to non-kid rooms and award you bonuses and mini-modes and whatnot. This and the gold-finding random awards wheel both give you a mini wizard mode upon completion. You can ride the boat (a lightshow hurryup), light the lickable wallpaper standups (snozzberries!), and so on. When you've done away with all the kids, you enter the final wizard mode, which is where all the bonuses built up before entering the factory come into play, as well as everything else accomplished. Like LITZ, this is a timed all-ball multiball frenzy, the aim of which is to build the speed of the glass elevator, and as the balls drain you watch the animation to see how far the elevator goes ("Gee, Mr Wonka, we've gone straight to the moon!" "Never underestimate the power of chocolate, Charlie"). A high score nets you a free everlasting gobstopper (gumball), if the operator has it enabled.
