I know the 'make it taller' comments are sometimes in jest, but I wonder if they dismissed the idea of making it taller to get the 'world's tallest coaster' due to the Saudi Falcon's Fury claim of taking that record. To my knowledge, they haven't announced how tall that will actually be? Imagine going to all the effort of making an existing coaster even taller, with the sole purpose of getting the world record, only to (potentially) be pipped again a couple of years later.
That's of course assuming something like that is even possible from an engineering perspective.
