In the stock headlights, there is a cut-off shield that produces the beam pattern. This shield consists of a piece of metal sitting between the bulb and the lens. If this is the same in the HID (and I suspect it is), then it should be relatively straightforward to dissassemble the Jspec lights and alter or swap the cut-off shields.
