Who wants to help me build a DJ mixer?

So I want to start on this pretty quick, it's my design for the simplest possible DJ mixer ever, running on batteries, no crossfader, just a switch, and the cueing and master channels are both controlled by the switch, so when you switch it to put channel A into the speakers, channel B goes into the headphones, and there's nothing you can do about it.

I still have to find a place for the audio outs. This is something I actually think I can accomplish with a bit of help at Sketch Studios.
