I understand what you are asking, but I am not sure you understand what I am saying. The impeller inside the water pump, which is responsible for moving the water inside the engine, is designed to flow a specific direction. By the way you are asking your question I am assuming your water pump is spinning counter-clockwise, or opposite of the crank pulley. If you try an make the water pump spin the same as the crank pully you are now trying to flow the coolant in the engine in the opposite direction it was designed to do. This will cause the system to not effectively cool the engine. It may result in severe overheating.
If you are wanting to get rid of your power steering, I would get a spare pump and rip the guts out of it leaving only the center part with the shaft going out to the pulley. You would be able to spin the pulley with absolute minimal drag and still keep the belt rotating in the correct direction.
