But how about a new quest item.

1 shot like Hammer or Orb. That would double the weight reduction on a container.

Or maybe just do a % off of it.

IE: you put a bag of loot into WashingMachine

Bag of loot normally 90% weight, When bag comes out it is now say 45% weight, or if just a % off say 10%, then it would come out 80% weight.

Limit of course on how low u could get something this way, 1% is current lowest possible, say this item could lower it to a best of say 10% or something.

Anyways that the idea, what u all think?
