Actually, some of your ideas are there. The original queue was very well themed & immersive, and it featured an early 20th century search team, deep dive suits, crates etc, a lot like the Everest queue, but a bit shorter version. The queue, though, has been stripped of some of that over the years. And the ride is set in the Scotland land of BGW. The land is highly themed to Scotland. When the Busch family ran the park, the Budweiser Clydesdales were housed there in an immaculately clean barn, the beer wagons, with an adjacent pasture. Scottish music and bagpipes were piped through the land that was immersive as all heck. It felt like you were in Scotland. And the coaster went through tunnels with Scottish fog and lighting effects.
