There are only two major obsicals I've come across for adapting Terra for the stage. 1) Falling out Le Parca's window and 2) The Sea scenes.
On another note, If I was doing Lost Cause onstage I would keep the episode breaks in. I'd do it as a play of 10 acts with the Narator do the recap every act. So it'd be a radio show, only on stage. Would be goofy fun. LC also doesn't have any scenes that need major ajust ment do to stage prop limitations.
