In spite of my love for the shows in that theater, I agree with Zimmy.
As a theater, it's probably past its prime. It was created for the purpose of elaborate one-person shows (not including animatronics/puppets), nothing more. One person shows might still work, but ELAB and SOCO put unique spins on that concept. That might be harder to do now, considering people have seen so many things before that they could previously only see in a show like ELAB or SOCO.
As I said before, the stage setup currently fits about six people comfortably/safely. If they remove the hearth, that makes it double the space (meaning roughly the size for an average BGW cast). The problem is that like Zimmy said, it's very cramped backstage. A good-sized tech crew cannot safely move back there for one thing. Another problem is virtually no fly space (above stage rigging space), and no wings (side space), just exits.
One thing that theater does have is adequate room under the stage for a small handful of actors and technicians. Interestingly enough; since actors and stage hands don't always get together, each performer learned basic tech work that tied back into "acting" and applied those skills in each performance. That "trading places" system was especially used later on in ELAB and throughout SOCO.
This meant that whenever you saw one Aaron(male)/Erin(female) on stage in SOCO; at least one other Aaron/Erin was operating Clancey, playing as Seamus, or doing other work backstage. This kept them each refreshed so their characters wouldn't get old like what you see in so many one-person theme park shows (some of which are also gone) including: Jaws, Disaster, Poseidon's Fury, and Jungle Cruise.
All of those issues aside- Busch Gardens has one big question: "Can one-person shows still work? If so, can they work in Castle O'Sullivan?"
