Bill & Ted
It may not be the biggest theme in the world but it'd build it's playfield (phonebooth/elevator lock) and ruleset (collect all historical figures, then party wizardmode) by itself.
As Designer I'd actually take anyone but Elwin. I like his playfield Designs and what he manages to get out of his BOM, but I'm not a pro player and his games lack a bit of... "charme" (FOR ME)? (Like compare "Deadpool"s charme to "AIQ".)
Since Jack Danger kinda "pitched" it, and I love what he did with JPdePin, I'd totally take that.
