I don't doubt your maneuverability at all, it sounds like the set of four wheels you pivot around has a pretty short wheelbase, meaning low scrub and good maneuverability.

Typically with a drop center you don't want to have CG perfectly centered, this only adds unnecessary teter-tottering and reduces your outside wheels contact with the ground.

Not necessarily, even if the CG is perfectly centered the robot will always be resting on either set of four wheels. I'm not too sure I understand your logic here, why would the robot not be able to turn in place in your given scenario?
