I think that a Mummy based ride could work well at USF without suffering a Twister-esque fate (i.e. attraction based on a forgetable movie). Despite being inspired by the success of the recent "The Mummy" remakes, and being marketed as such, so long as long as the central theme to the ride is the mummy monster, everything will be fine.
The Mummy is a classic Universal Monster, and long after the apeal of the Brendan Fraser versions wears off, it will continue to be remembered as such. Years down the line, people will just assume that The Mummy ride housed in the old "Kong" building is based on the classic Universal Monster movies. Lets not forget that "Kongfrontation" was based on the 1976 "King Kong" remake, and it's follow up, "King Kong Lives".
