I thought of that front position before, but on my other bike I had something there and the forked compressed and broke it (I think it was some small aftermarket running PIAA lights?).
Have you compressed the front fully to see if it won't hit it?
I thought about making some black plastic box above the license plate in the back and try to make it look like the original and leave the lens in it to somehow appear stock. Dunno.
