Why don't you make (something like) goblin caves?
You could place them like any other building (cannons, archer towers,...) and depending on its level you could train goblins who would steal the loot the other player has already stolen. They shouldn't deal damage and they shouldn't steel really much loot but the player would at least not loose all his elixir, gold and dark elixir. The loot should be save in the caves.
