If I understand what you want, I think the way I'd approach it is to duplicate the CoronaLight. One would be set to Shadowcatcher illuminator, with "Visible in reflections" off, so it would cast shadows on the plane but not reflections (and no reflections on other objects either) and probably set to exclude all objects in the scene except the plane so it doesn't contribute lighting to them; now this one is simply casting shadows onto the catcher.
Then a copy of the Light, Shadowcatcher illuminator off (so now it contributes nothing to the shadowcatcher), with Reflections on, which will cast light and reflections on everything else, but not the catcher plane.
Of course, this is "not physically realistic" because in real physical terms, the light should be reflecting off the ground plane too :)
