If your goal is to minimize the wires, then you'll have a good result. Keep in mind, though, that the receivers that you need to connect to the QS4/8s do need to be powered, so you'll at least have a thin black cord running to the speakers.
If your goal is to have great audio, then your result might not be so good. I can't speak from personal experience, but I have a feeling you won't get the same fidelity from most wireless audio transmitters as you would with speaker wire. There may be some great products out there though. Did you have a specific product in mind?
