Carbon Fiber Wagon Hatch

This is gonna sound crazy, but I visually remember following someone on Instagram or Facebook that had a wagon and was doing a carbon trunk on it. I can not find it anywhere anymore. I know they make for sedan/coupe and I know there isn’t a company that makes them for wagon, but I’m sure with all the carbon technology, it can be done. Please tell me someone knows of this... Would it interfere with the weight for the power lift gate?
