Amazing. I want the same thing, if not exactly, pretty close. I think your proposed mixer would work for me in any case.

They might have a few components, but not all.

You don't want diodes. The proper way to do it is to build a multi-input preamp. You might get away with directly mixing the outputs of the devices, but diodes will clip the signal. You're working with AC signals, not decoding a keypad matrix. No diodes.
Unfortunately, while I know what to do in general, I don't know enough to properly design what you want.
http://www.digikey.com/ has a lot of neat stuff. Be aware that there are those who hate them, but they're worth a look.
