 The stalks are only needed to get the indicators within 400mm of the edge of the vehicle.If they were built into the headlights that wouldn't be a problem as the headlights need to be within 400mm of the side anyway.
 I suspect where they would fail IVA is with the headlight beam pattern, as presumably they 'kick' the wrong way with them being from the US.
 Still a nice idea though!
