If there was ever a creative team that could make a tour of this show happen, it's Chavkin, Lien & co. They're all superbly talented and inventive, and I imagine there are multiple ways they'd consider touring. A tent sounds the most promising, but then again, costly. I can also imagine a world where they build a touring set that sit inside a proscenium, with risers and the basic runway set up that they have at the Imperial. The rest of the theater wouldn't be able to be transformed, but you'd still have the essence of the show presented.
