Multiple light baked textures for one mesh/model?

Is it possible to have a static model where there's multiple light baked textures, say one with a nearby light on and another where said light is off? I don't have the money for dynamic shadows but only need those 2 light on/off states for a few areas, it sounds simple enough to be possible. Or, Lightbaking one version of the model with the light on, lightbaking another version of the model with the light off. Then I could just switch the renderer.active thing. Although, if both models were in the same exact place in the room, would the beast lightmap engine just automatically bake the same way?
