i did some additional reading. in the discussion thread below, the guy who seemed to be considered a suspension expert by other posters brought up an interesting point regarding low speed vs high speed damping, and the fact that compression/rebound clicks open/close needle orifices that control low speed damping, while high speed damping is controlled by the shim stacks. light weight wheels impact high-speed damping, not low, so if anything, they'd be more likely to require a shim stack change than comp/rebound adjuster changes.
interesting discussion either way.

highspeed and low speed damping are indeed different.
changing the mass of the wheels impacts all damping. High speed or low speed damping is determined by the speed of the wheel to get over the bump, nothing more. The less time the suspension has to react to the bump with an adequate suspension stroke, the more likely it is to be a “highspeed” event.
a higher degree of adjustment may be required to highspeed damping, since the elapsed distance of energy applied and returned by the spring is greater.
again, much of this is academic, and often times what can be calculated as fact on paper has little real word impact that can be perceived.
