It might be quite fun to explore it back in prehistoric times, although I know Ghosts of Albion is never going to go there. I can just think of some quite amazing and bizarre electro-acoustic or Stravinsky-esque sounds you could do to match the bleak or lush landscape depending, that would be great fun.

A future one, done in about 2300, that might be quite interesting. You could do some real experimentation. Because then today's pop music would almost be classical music by comparison, so you could put lots of drum loops and things in, intertwine that with some orchestral things, and some interesting textures of electronic soundscapes. That would be good fun to do.
