The current issue is we all have the modern technology to see when calls are missed.  

The last time I looked at data regarding statcast/hawk-eye data, the median error is like +/- 0.25 inches and around 1 in 20 or so calls (around 2 stdevs) were +/- 5/8 inch.  It's almost certainly better for pitches that are clearly in the zone or clearly out of the zone, but you're going to have consistency issues because when it misses it's going to be in a random direction.  On the other hand, human umps tend to miss in the same direction, resulting in a more consistent zone.  While there are merits to both, you're likely to find players that would strongly prefer a consistent zone, even if it's consistently wrong in some instances.

 

You'll get most of the benefits of human consistency with a challenge system, but I wonder how it's going to be handled if you challenge one and hawk-eye gives you a wacky result that would overturn a correct call.  There would need to be human cross-checker to disregard bad results.
