I understand you preferring something other than the WeatherTech floor liners but they are the gold standard. I can't tell you how disappointed I was with even the WT rubber mats vs. the floor liners. The Liners just outperform by a wide margin.

Maybe an option to customize the WT Floor Liner would be to remove the WT sticker on the Liner (it eventually comes off anyway) with an RS7, Quattro, or Audi rings decal/sticker/badge. You can source them from numerous locations, including Ebay, and I believe there is a thread on AZ where someone "seals" the rings sticker with a clear film.
