I would say that you could do this in *a* layer switcher just as easily
with WMS as with MapServer Layers -- either one can accept multiple
layers in a request. However, I believe that this advanced level of
functionality belongs outside the OpenLayers.Control.LayerSwitcher.

It is a good idea in general though, and might help solve your problem.
