All that sounds BRILLIANT to me.
I visited London a few years ago and went to the Doctor Who Experience. Google it to get an idea what it is. Basically an exhibition of Doctor Who but with an interactive experience too. This included a couple of well themed ride components (inside the Tardis), and used a combination of live actors, animatronics, and filmed sequences featuring the current Doctor Who cast, and various special effects.. That's something I'd LOVE to see in the Gold Coast, and Dreamworld would be a perfect spot for it!
Or (and I know I've posted this before) something like this video by theme park review shows.
