The sway bar is there to help transfer weight while on a curve from the outside to the inside of the vehicle. It really works when you are on a tight corner or need to swerve. Sure changing the springs changes the characteristics and may make up for some (possibly all?) of not having a sway bar but that is an unknown. If you do a lot of highway driving and need to swerve at 65mph it's kind of a poor time to test the roll over characteristics of your vehicle isn't it?
Just something to consider. Like standing on the top step of a ladder
