Maybe you should try to mount an A/C clutch on the power steering pump. Seems like that's the easiest way to get what you're after.

Using electric power steering in conjunction with a traditional rack, like what Chevy does with the Cobalt is quite effective. The Cobalt which is no lightweight is rated 37 highway.

However, going to a purely steer by wire system is a big no-no. Think what would happen if the motor burned out or you blew a fuse on the highway. I don't see mechanical racks disappearing any time soon.
