I own a tunze wavemaker, so i have an idea of what you trying to similate, but i dont think its going to work without the proper controllers. All that i forsee happeing is you pump the well empty and then get air bubbles and noise and pulsing the motor on and then off every ten minutes will have very little bennefit IMO.
If you can get your head around the idea, why not try and create some sort of plunger that plunges into the well pushing the water out the hole and then it lifts up again sucking water back into the well. Will have a very similar effect. You could run with this idea and even make it sort of cantilever so that the plunger plunges one side whilst the water pushes the plunger up on the other side and vice versa.
