I do want to keep the title "Ecclesia", it's quite unique, and the direct, parliamentary democracy I like. As for French Revolution, I have no strong feelings on it one way or the other. I think there are bits here and there which I like but a full blown one might be stale.
Republic City is something which has also interested me in the past.
The harmony and balance the taijitu represents could be a consideration, but that could also be trying a bit to hard to make everything make perfect, matching sense.
