Attack NES keypad for massive damage

Check out this uber huge NES controller that can be found outside on a game store window display. It looks pretty cool and all, but unfortunately, it doesn’t work. Does anyone else have the time and technical expertise to improve upon this version and make a working model? After all, there is nothing quite like punching on large buttons while you’re trying to guide Samus through a treacherous cave. Come to think of it, this giant NES controller kinda resembles the original Xbox controller when it comes to size.
