I think I find myself wanting a little bit of a tactile dot or something on the button, so as to more easily intuit which one to press. You could even retain the switch's ability to flip around the controllers, if you just put all the tactile dots on the outer radius of all the buttons. Like, put a little bump on the top of the top button, put a little bump on the bottom of the bottom button, etc. The only thing I can't really figure out is how you might refer to that in a game, or refer to that visually in a way that makes sense, other than maybe just building that association over time. But yeah, having them be distinguishable tactily is, I think, a good idea.
If your plan was implemented a simple graphic of a circle with a dot in the corresponding quadrant would work.
