The only thing left i suppose is a play field that changes. i.e the pop bumbers disappear below the play field and some drop targets come up or the ramps change shape.

Um - actually one pop bumper does disappear on CV. Drop targets do tend to come up when energised. Diverter ramps do kinda change their profile.
Otherwise you have a pretty wild concept, albeit unfeasible?
Drink enough piss and it will all appear to happen anyway . . .
