Raising rear end

I am curious how I would go about lifting the rear end. I was thinking if I take the rear mount of the leaf springs And mount it parallel to the ground versus perpendicular I can get a bit of lift. Any idea I have to do that would be to take a piece of square tubing weld one end then slice it corner to corner so I have an angled piece. Then just use the standard mounting point for the rear and drill new holes in square tubing for the mount.

Any other idea?
