Yes, you can almost always use roll bars to balance out mid corner. Changing the roll center actually has a few other interesting attributes, however, which often make it preferable.
First, as the car rolls and roll center changes height you can move from oversteer to neutral (for example). So this is one of the few knobs you can turn that will allow you to adjust mid corner and corner entry balance separately.
Second, simply adding extra spring rate (in the form of swaybars or primary springs, doesn't matter) hurts overall grip all else being equal, as soft is sticky. So there are reasons why you'd prefer to get the same control of the body motion with softer springs. Which is of course why anti-squat, anti-dive, etc suspension is a good thing in the first place...
To say it gets complex is a mild understatement.
