Are low-armor and low-HP units useful at all when going for no losses?

Inquisitors? I found that they just revive a tiny bit of HP, is that because I had too few of them in my stack? If I lose 5-6 Royal snakes, can a stack of Inquisitors bring them back? Can a full stack of Paladins/runemages/inquisitors being back a whole stack?
