@herb_fargus Thanks! I had considered doing just that when I was making the first one, but I decided that I should use up the couple of knock-off SNES controllers I had kicking around. When I made my final template, I actually put the holes for the USB port on both sides so that if I revisit this, I could just make a double USB version. I hadn't thought of a quadruple USB version, but that would certainly work as well.
