Idea of mod, earn the cost of what you kill or destroy

Age of Empires II: DE II - Modding

Hi,

I have an idea of mod and I don’t know if it could be enjoyable.
It’s for FFA.
When you destroy a building or kill an unit you receive what it cost to produce it. It’s mean if you kill a villager, your earn 50 of food, if you destroy a castle(remove the last hit point) you earn 650 of stone.
Does it could be fun to play to that?
