Here are some ideas that aren't necessarily historical or exact references to groups of performers:
Revelers--this could be the name of a specific group or a generic term for a wide range of performers
Theatrics/theatricians (that sounds like a technical term from a sci-fi dystopia ruled by our AI overlords)
Tivoli--place name (for several different places) but I like it as an answer for the question, "What do you call a herd of actors? A tivoli!"
Vaude-villains--this is obviously for a very bad variety act. And I mean bad in the most deliclous sense of the word.
Fantasists--probably too loaded with modern meanings
