Well if conditions don't permit for the QS's then they don't permit. Since it sounds as if you're more concerned about looks/concealability than performance at this point, then I would say Orb would be your best bet. There are a few companies with wireless surround speakers, but as I'm on my phone right now I can't Google them.
Keep your QS's nicely boxed up for your next move. Having gotten used to the superior sound of your Axioms, you'll surely be on the market soon for a house with a more accomodating listening room!
