I've often wondered about adding an electric motor to run the water pump and power steering pump; as you said a steady rpm would be all that is necessay, and in the case of the PS pump you really only need it during slow driving and parking or emergency maneuvers. Wonder what the fuel savings would be on using an electric motor for the water and PS pump.....

Only other accessory running off the crank is the AC and alternator, neither of which I intend to delete (I'm a big baby when it comes to sweating )

This discussion nearly makes me want to add some lead weights to the flywheel to see how it goes.
