demolish Junklot stunt coaster, build a new, bigger, better version of Phantom Theater with over 200 animatronics and an actual theater you get to walk through after the ride is over with skeletons and dead people sitting in the seats.
demolish Invertigo, the outdoor theater and congo falls, put in a wing coaster in that spot.
put a ground up single rail GCI where Vortex once stood, I would make it themed to a snowy mountain and call it "Polar Vortex"
demolish the tomb raider building and put in a bigger and better version of Congo falls, give it an indoor section with zombie animatronics and call "Zombies of Kenton Cove.
