IDK if they'd ever do this (but they have unmasking, so who knows?) but I'd pay an upcharge to watch a special Horror Make-Up where they just demo a house look or two for that year. Doesn't have to be an IP character, but would be so cool to see how they put a look together, what techniques they use to make sure it stays, all that.
Would be pretty simple and a cool thing to highlight TMs who bring the event to life
