Replacement Pro Controller faceplates with octagonal stick gates?

Does anybody know where I can buy a replacement faceplate for my pro controller that has octagonal stick gates instead of the circular ones? I want to switch to the pro controller for Smash Ultimate, but I really miss the octagonal gates from the GameCube controller. It made angles so much more consistent.

If nobody is making them, they should start. I think they would sell like hotcakes!
