Uncorrupting orbs? Maybe

I'm not very smart. I don't know what kind of balancing would this require but it sounds fun to me. With some limitations, of course.

An orb that uncorrupts an item with the drawnback of restoring the implicit mod to the base's default. It can't be used on items that are corrupted by default (e.g Skin of the Lords). It can't be used on uniques that turned into rares.
It may allow you to fish for a specific corrupt implicit if you're lucky.
Something like "Orb of Cleansing/Purity"

Again, I don't know the implications of this. It may very well be a dumb idea but that's how humanity progresses.
