dessert well upgrade

how about you make it so if you drop gold into the dessert well it will give the player the luck effect .if its a gold nugget 1 minute, gold ingot 10 minutes, and a gold block luck 2 for ten minutes. the luck effect could not only give players better loot from unopened structure chests but it could give better items from suspicious sand/gravel and upgrade the trail spawner loot that you get from defeating waves of enemy's.
