Let me see if I understood your rendertree, you are rendering your beauty without any shadows right? then an FG pass which you add to the beauty pass two times, one normal and one darkened and masked with the shadow pass.
It's being a while since I've rendered in this kind of components, but light should be treated as an additive thing. I would render the beauty with shadows, and add (plus) the final gathering to that pass, if you want to change the color and intensity only for the shadows I think I would resort to making a new pass, override the surface port of all the objects and connect a white lambert. Then you got your shadows and self-shadows without resorting to the shadow shader. I mean it's not physically correct but for your purposes might work.
