Builder huts and achievement.

I think it would be really neat to have visual upgrades with the achievements that we earn. Builder huts for example, when you complete that union buster achievements it could upgrade its looks. Like having all 3 stars would give it a golden trim, or 2 stars having a silver trim. Another example, the gold or exlixar achievements, having all 3 stars would put a different trim, gold with black, on the storages you have. I think that would be pretty sweet, when people look at your base they would see the achevements by looking at your buildings. Any more ideas would be great! Thanks for reading.
