99 Purple XJ

I Welded my jcr rock sliders to the unibody but im cutting the legs off of them and welding them to the rocker would it be strenthen the unibody if when i cut the legs if i weld tube to the legs were i cut it off and it runs flush with the unibody? The 2 plates that are connecting the sliders legs to the unibody but i want to cut the mounts flat and weld tubing to the plates already on the unibody would it serve any strengthening to the unibody
