You will lose roll stiffness. Why do you want to switch?
The only advantage would be the truck will be even less likely to over-steer with the smaller sway-bar, and maybe a better ride on some surfaces.
The truck has the trailer package which includes helper springs. I've added air bags and polyurethane bushings, but I still get a lot of rocking around, especially when I'm turning while pulling out of a driveway. I thought maybe the original sway bar might have weakened some with age, or that the Hellwig, given its sterling reputation, might be of substantially better stiffness in spite of its smaller size. Also, I've tried more and less air in the airbags, but I haven't noticed much difference.
