I thought the Fire Ship would be most appropriate for any Yuan naval unit to have as an extra ability when they're low on health. They'd basically function as a missile that could be used against nearby naval units and cities. I imagine that'd be tedious to code, though.
This sounds like an excellent idea IMO. I think it's possible to code, not sure. It could still be classified as a ''unique unit'' that ''appears'' when a naval unit is low on health. Basically, check if the naval unit is low on health, then replace it with the fire ship, while it's still counted as the same unit. I've a land unit that turns into a Privateer when embarked, so it should be possible..
