The idea IS interesting, but it wouldn't work. It would be a mere copy of the original process, and nothing would be as organic and personal.
The original dancers that took place in the taping had no idea that they were telling their stories for a Broadway show. It was a "dancer's project" idea, and nothing more. Subsequent tapings were made knowing there may have been a workshop, but the unknown future and exposure is part of what made the stories so personal and organic. It can never be duplicated.
