I agree with many of the posters here. While it can be a great deal of fun for the designers to design these rides using heavily themed assets, it may not be the best idea for the end users. As suggested interchangeable themed assets within a ride would be a great compromise and solution.
Its like legos, the more heavily themed a piece is, the more useless it becomes in the long run.
