If you can find a decent 6PDT switch, it's very possible it would work. The alternative is to essentially build a 6PDT out of relays. Though I'm pretty sure you don't need to switch the subwoofer, so you would only need a 5PDT.

The following information may make it clearer, it may make it worse. if you don't fully understand I don't blame you, just disregard it. There's no real solution here, just some background on relays.

Most relays have a NC and an NO contact. NC being normally closed and NO being normally open. The common pole is connected to one or the other depending on if power is applied or not. NC and NO are based on when there is no power applied to the relay.

Basically this means when your switch is off (open), there is no power applied to the coil of the relay. When there is no power applied to the coil of the relay the Normally Closed output leg is closed (on), and at the same time the Normally Open output leg is open (off).

When you apply power to your relay coil. the NO leg is closed (on) and the NC leg is OPEN (off).

So in your case you would have the input coming into the common leg, and one set of outputs connected to the NC and one set to the NO.

I would highly suggest NOT combining your center and left/right speaker channels. It's typically not expected when the receiver company builds the receiver and you don't know what will happen when the power is coming/going from different channels.

My solution would be to add an additional center channel speaker and switch between the two instead of trying to mix the audio signals. If you're only using 2 channel audio you may not even notice that you don't have it..

EDIT: To answer your question in the other forum, yes you would need a power source to operate your relays. An old 5V wall charger from a cell phone would probably be your best bet.
