I was reading something about the Paris Commune in 1871 (during and after the war) and I asked myself : why we couldn't play a french communard faction ?
She will be consisting of french line infantry, the Garde Nationale and group of armed citizen marxists (red flag) and anarchists (black flag).
Maybe work a map of Paris's Wall for the sieges of the city, etc...
I believe that it could be interesting.
Sorry for my frenglish
