Also, I notice your avatar and your location is Montana. We were looking to snowboard at big sky, but it's expensive. Also coming from Atl didn't help either.
Ooh! You should TOTALLY come to Big Sky! It's my favorite resort on the planet. I am biased, but I'm serious too. That's actually where I am currently. But yeah, I'll admit. Airfare to get here isn't cheap unfortunately. For cheaper lodging, you should think about renting a vacation rental. Check out www.VRBO.com

. PM me if you end up coming, and I can give you the inside scoop and perhaps I'll see you on the hill for a few turns!
Back on the original topic, I still think it'd be easiest to go with that selector or something similar. You COULD probably get away with splicing all your wires together and hooking them up to the AVR's L/R channels directly, but I'd be seriously concerned with damaging either your speakers or amplifier. Especially with having to rely on existing equipment of which I haven't tested myself and me trying to more safely give advice over the internet. Whichever way you go though, keep in mind that for every speaker you have tied into the same channel though, you are effectively cutting down the volume you'll get out of each one. By the time you're talking a dozen speakers, you're going to have to seriously crank the volume knob to get them to a listenable level, which could be very hard on your equipment.
Thus, if I were you, I'd probably go with your AVR connected to a separate multi-channel amp as recommended above to maintain good power to each speaker while minimizing any risk to your equipment. Personally, I'd want dedicated system like the Niles MRC-6430, as opposed to an AVR, but we're talking more money there. I know you don't want to buy any additional equipment, but that's kind of the most ideal thing for home-wide distributed audio like your house came with. I'd be curious what the former owners of your house were using in that closet.
