I'm not aware of anything like that existing, or having existed, and if it did, I would have seen it around here (WOB/BS).
But I recently saw a Golf6 GTI and an Rxx on the highway, still somewhat disguised.

Audi A4 B7 Cabrio 2.0 TFSI/BWE - sold
Passat Variant Highline 3BG EZ 2/04 2,0 TDI mit DPF 235tkm 2x DPF gespült - RIP dank LKW
It's probably been about a year, and at that time I hadn't had anything to do with Golfs yet.
I've even seen one "in person" with the Rittal enclosures. It looks a bit strange because the internal lamps (in the door) don't leave much space for the standard NSL (Non-Standard Lighting).
