Sounds like something the requires more than 10-15 seconds per scene to have any effect. What would be the ride vehicle? Would you be a passive or active participant? Why would BatB be better than Sleeping Beauty or any number of other potential properties for a dark ride environment? Why would a movie that has such a strong appeal from it's music work well if it had to cut it's songs down to such a length as they would loose their impact?
Gaston's hardly a thing to be feared or chased at like the Witch in Snow White (who'd, along with Maleficent have much scarier dungeons), a Library isn't nearly as exotic as Neverland and there's zero opportunity for any kind of surrealism like Mr. Toad or Alice in Wonderland (another key ingredient of a good dark ride).
The stage is a place to tell a musical about two people folling in love, not a theme park ride. I'm sure all the sqeauling fan girls who insit it would be great would be mightly disapointed by the end product.
Your dinner theater would be much better, and that's something you are getting supposedly (along with a whole village). Think about fans about just about any other Disney property who have to put up with much less representation in the park.
