Leverage boosts for endgame play

I'm a boom beach player as well as clash. The recent update in boom seems like it would have great potential in coc. SC added seasonal boosts to specific troops and defenses. You use loot to purchase a special resource used to make the boosts. I'm at the end game there and its great because you have nothing else to use loot on. Why not something similar in CoC. Use gold, elixir, and de to purchase a new game resource to boost the offense of troops or the defense of towers. It could add some interesting game play and give those at the end game a reason to farm. The boosts only last for a few weeks before resetting. Players would farm because it would give them a war advantage to use the boosts. Thoughts?
