One suggestion is to make it a government you can use to stop a greatly superior attack. For this crusaders/fanatics would need to be reasonably cheap and have very good defense (defend ok against a musk or frigate). Something like A2 D3 HP10 and a 2x defense bonus in player's own cities while in Funda. So extremely defense oriented at the cost of 4 turns of Anarchy and a lot less science. They should also be reasonably cheap so they can be produced while under attack.
Funda is currently useless.
