Builder Idea

Ok so i look my builder upgrade my Archer Tower and i got an idea : if i have 3 builders ( example ) and i want to upgrade Wizard Tower to level 8
it will take alotttt of time, so the idea is to use 2+ builders for 1 upgrade i mean if it takes 14 days so it will be 7 days
if i use 2 builders, you can use this option only if you have 3+ builders :

3 Builders = 2 Builders For 1 upgrade
4 Builders = 3 Builders For 1 upgrade
5 Builders = 4 Builders For 1 upgrade

* Its sure will be only option, you not must to do this, and it will sure cost Gems :)

Hope it will be on Clash of Clans !!

Thanks !
