I had originally planned on using a single PSP1000 joystick, but I like the joycon joyticks a lot better. I was wondering if it was possible to use them with with of kite's saio boards with the pi3 gpio extender?

And here I was thinking I wasn't blind!

Any chance you could make a parts list? I've never forayed into the world of RPi, but after seeing this I've decided to give it a go. Maybe a touch ambitious for my first project, but I like stumbling along the way with things like this.
