Unfortunately, like the Yeti, Imotep is a complex animatronic involving a lot of motion.
There is a reason that recent animatronics are like the goblins is Gringott's, (an homage to an opening day MK attraction, The Hall Of Presidents.) Even the awesome Kong animatronic isn't in beast mode. Which plays into Kong's pensive nature.
I think animatronics like Yeti, Imotep, and such are a dieing breed at Universal parks. They are stupid expensive, a maintenance nightmare, and really don't add that much to the ride experience. Even at his best, Imotep always looked like a robot on a stick.
That said, has everyone seen the new Elsa animatronic in HK? Amazing! Dibs on how long before we see a TikTok video of her having a seizure with hydraulic fluid leaking from her eyes?
