A high intensity hyper or looping variant from B&M would probably only work in Hollywood Studios. We might get another Rip Ride Rocket, but I don’t think something that intense would fit MK or Epcot.
A high intensity coaster in the forest would also work in Ak, but it’d have to be something like an Intamin Blitz. Something too tall would break AK’s treeline which would not be ideal, and that park already has a mine train and flying attraction.
BTMRR shows Disney can build something incredibly themed, and 7DMT shows that they can combine show and thrills. Make something longer and extremely well themed, and it’d be pretty well received.
