Even when shows were at Radio City they used small simple set pieces. Yes, because it IS very expensive and things have to move FAST on a live show. I worked on the set piece for Wicked a few years back. This was one reason I think they aired the Car Ride Karaoke, to give the set crew time to rearrange things backstage. It was breathing time. The screens, for me, worked well and I know eased things up a bit for Set Crew and Stage Managers.
