"Old school Disney" never did anything like that so I don't know where you got that idea from other than to concoct an imaginary complaint about contemporary Disney who
never do anything interesting. You're not alone in that on this board don't worry
But yeah, the idea itself would be neat, the dark ride could be a chase in and out of the different doors and you'd have the coaster swoop overhead in the monster world side. Nightmare to sync for stoppages etc though so probably couldn't reliably choreograph anything.
