The vaccum operated systems on most carburated engines was designed to keep the intake air at a constant temperature. This way the air had some consistancies flowing throught he carb.

A servo/stepper motor should control the mixing valve easily enough. Even though I have no idea how to set up a controller

One thing everyone who uses a WAI says is that power is reduced. If you tie into the throttle position sensor you could have the valve go full cold at a designated position. This would provide a few more ponies (close to stock) when absolutely needed.
