Yes it has been done. The guy that did it is named Ed (or rather I should say that's the only person I know of that has done this) and he should have a thread about it on SL somewhere. Seen it in person and it looks ok. Let me know if your interested I can get his contact info for you. Last I heard one of my friends said he was talking about setting a weekend aside and getting a bunch of people together and working on their third brake lights (not sure if he's done it yet, heard that like mid august). Not sure of your location either but he's in the bay area.
