The direction of the incoming ray doesn't matter. Brilliance only uses
the angle of the light ray to the surface normal, what you would suggest
would make it look like all radiosity lighting was coming from the camera.
You would have to do it for every radiosity ray, using the direction of
the radiosity sample...and I don't know how this would interact with the
interpolation POV uses.
