Frame rail relocation VS Narrowing rails

I can picture this but probably not accurately describe it. Cut the stock frame rail where the tire would interfere, the whole thing meaning the rail as if it was a new piece to be installed. Using, I'll guess, 2X3 tubing, move that piece of frame rail in to clear the tire. The rear part of the frame rail remains in factory location and so does the front part. "Outriggers" would have to be made for the shackle mounts and the front spring mount.
How about a "leaf-link" set-up?
