In addition to your copy of Fishbowl, I will implement your "light scene" idea, and publish it inside Fishbowl for all our users. Your idea needs to work with simplified lights and changes that don't depend on a specific stage layout or backdrop. We're setting a mood, not recreating an exact image or scene. For example, a friend wants a "blues bar" atmosphere. We've decided on a rotating shadow at the feet of the performers that suggests a ceiling fan, and a blinking blue/blue/blue/red light that is reminescent of a neon "open" sign.
