Have any of you guys done this?

I got to looking at the hangers for the leaf springs on my truck and before I bought a lowering kit for it I got this crazy yet cost saving idea. I basically wanted to know if any one have taken their hangers off and cut the top of them off and simply moving them up so that it will lower the back end. Im sure you would have to re-drill holes on the frame and you definately have to drill a hole at the bottom of the hangers.
