Turn around room for a reception

I want an sophisticated and elegant August wedding. However, the venue is in a old community church with beautiful stain glass windows and open space. We’re using the space for both the ceremony and reception. The caterer told us that 1 hour is not enough time to change from a ceremony to reception set up. He suggested that they do a turn the room. How can we pull off an elegant affair if we use the turn around room concept? Is it possible?
