You would need to write support for them, though, right?

A "dongle" swapping those pins should be easy to build.
Yup, the 3-button pads are really easy to support: pin 7 high = buttons B & C on pins 6 and 9. Pin 7 low = buttons A and Start on pins 6 & 9. So yeah, it still needs software support. (The six buttons pads can also be read by pulsing pin 7 with the correct timing - they multiplex the direction lines as well as the fire button lines.)
