The Rataouille Ride really is cheaper for TDO than MI Coaster,or New Countries for WS. I am saying this because the attraction actually would cost TDO less since the attraction is already being work on at Walt Disney Studios Park. The fact is TDO doesn't have to pay for the Research and Development of the ride unlike what is happeningSeriously. I could think of at least 100 projects I'd rather see than the very expensive Rataouille ride.
How about the MI coaster at DHS? SW land? New countries for WS? New Imagination? Replacement for EO? Replacement for Energy? Carsland?
TDO doesn't mind doing attractions for another park when the R&D and other costs are already paid for from another Disney theme park that isn't in Walt Disney World. TDO does have history of bring attractions that already were paid by other Disney theme parks world wide like Soarin', Little Mermaid attraction, and Fantasmic as examples.
