I don't know about the biology; make sure you experiemtn on yourself first.
Things like this might fall under FDA approval, I don't know.
2-3 Watts sounds like a lot.
Your ideas are good in an economic sense; using existing technology. Technically though you might have to build your own amplifiers to get the 20kHz out.
You might think about the TI class D amplifiers (if they will work with the Piezospeakers).
