LA Ermor's Dominion Change in 3.15...

[Wick]

Once upon a time (dom2) I toyed with a choir nation. It would have been based on the Call God mechanism to summon angels ranging from Putti to Angels of the four hosts to unique angels, with a little bonus if the paths of the Singer or Matster of Harmony matched what they were calling. The Celebrants were troops that could join a Singer and there would obviously been spell songs. The troops were weak and the mages overpriced but calling units whose priestly abilities would let them call more units would probably have made it a late game powerhouse.

Another non-standard economy could be your basic d&d goblins. The troops would freespawn but cost upkeep so you have to keep attacking your neighbors. Although this might not work too well given the clever ways people found to dispose of militia. Hmmm...
