This sounds cool. I'd be very interested in an insert that we could install in a NBS taillight to upgrade it to all LEDs, but that keeps the whole thing fairly stock looking (no fancy flashers or designs or patterns, fairly conservative looking . . . I know, I'm a boring person

).
Keep us posted on this, I take it he's looking into the OBS ones right now but I'd bet there'd be just as much interest here in the NBS ones too.
