How would that work?
Good question! It could work similar to how the Dirtywave m8 works. Basically having the cursor snap to the grid and having button combos, long key presses, and other buttons to control the interface and input data. Ladd is another example but both of those are limited in the amount of buttons they have so doing it for regular gamepad with have the added benefit of all the extra inputs available! Just a thought though :D
