Viola it does work! well kind of works...
Stupid Revit does not accept alpha channels through glass (which is the whole point, as you want the reflections), i.e. interior views looking out you need to turn off the glass. Exterior renders are fine, also if you want to use this technique with hidden line views with shadows on... ensure you do not use a gradient background.
