Not necessarily. If you calibrate the strike zone prior to each at-bat, as a hitter, what if you crouch more or less after that? The strike zone is immediately thrown off. And while hitters' stances are generally consistent, even an inch or two difference in a stance can throw off the zone.
In theory, you're right that you could achieve a more consistent strike zone. But in practice there are a few things that could greatly diminish the accuracy advantage you gain with the system.
