I decided to drop the Wii Nunchuck as I just got tired of it(and the accelerometer in it sucks), and my plans exceeded its capabilities. I went ahead and made my own custom controller, with joysticks and pot triggers. I plan on also adding in better accelerometer for the fun of it, but neither that nor the necessary multiplexer board have arrived yet (because everything requires analog inputs). I haven't finished everything on the inside yet, but here is a good look of the outside.
The red covered switch is the "fire switch" which will be enabled in the future when I hook up the pan and tilt laser targeting nerf gun.
