This may be an unpopular opinion but I think if this ride were to ever get a bit of a redo, I'd... genericize it, a bit. As in, remove most of the direct story references to the Mummy movies. Instead just keep the same tone, atmosphere, etc. of the ride, but make it into a timeless, standalone story instead of plugging in a super old film series that's already been unsuccessfully rebooted. I feel like the attraction could stand the test of time and appeal to more people if they went this route, IMO. But I know it'll never happen since everything has to be IPs at UOR.
