From what I understand, the headlight housings are the same, but what's attached to them on the back side is not. The projector/lens is identical, but the wiring for the bulbs between halogen/HID obviously is not.
Doing an additional search on a parts site only identifies the options for your year as "with or without fog light" in the comby lamp assembly.
You should be fine with buying a PnP HID kit in your bulb type and putting them in.
