What an earlier USS Midway could have added in World War II

How effective would USS Midway have been in World War II in her original configuration?

Very effective once doctrine caught up: she would be a large, tough carrier with an air group well suited to independent raiding as well as fleet operations.

Midway is described as a powerful additional fleet carrier whose full potential would depend on the maturity of aircraft-control and fighter-direction doctrine. If she arrived during the early carrier shortage, the U.S. Navy might initially try to operate more aircraft than its control methods could manage effectively. By 1943 the fleet would have time to learn how to exploit the larger deck and air group. Her durability and reserves would then make her especially useful for detached raids with cruisers and destroyers, absorbing aircraft losses longer than a smaller carrier could.
