Rob at East Coast Buggies makes them. I've got one on my bug. Semi-W though not a full W.
https://www.eastcoastbuggies.co.uk/Bonding the hinges to it makes it function like a normal decklid. I used a QR pin on the bottom.
This wasn't the decklid, but a baja bug eye bonnet I did, same technique, some good structural epoxy, few clamps and a donor bit of sheet metal.
