Looking at it another way, this would allow me to turn off all layers and just have a blank map. I'd also like to have the "Base Layer" portion of the LayerSwitcher disappear if all my layers are Overlays.

Nope.

you can use displayInLayerSwitcher as a layer option to turn off the
display of the base layer, and set a non-visible baselayer (like an
instance of the OpenLayers.Layer class) as the baselayer of your map for
a similar effect though.
