wouldn't the coils spring and shocks keep the side to side minimal? i know they won't stop it but at least prevent some of it. and if you don't have a sway bar, it is gonna roll anyway. i cant think of a reason that it would move around anymore than normal. I guess i would just go with heavier springs to counteract that and deal with the rougher ride. you are just talking about driving it off road anyhow arent you. I would personally like to try this being less expensive but i want to be able to drive to places safely.
