The other thing that can be done depending on engine bay space is to get a small DC motor from a treadmill and just use that to spin the existing PS pump. It's extra battery draw, but you could always make it switched - turn on when you're in the parking lot, and off when you're on the road.

Heck, with a little luck and electronics knowledge, you could use an arduino hooked into the VSS to measure vehicle speed, and have it fire a relay to turn the pump on and off automatically at some speed (off if speed is higher than 20 MPH or whatever, and on if speed is lower).
