Waiting time is not the only consideration, safety is, I would argue, more important.
Human beings are also somewhat more complex than a mathematical term. Queue theory is not 100% accurate in predicting outcomes. For example, it would predict the wait time to be higher for cars, because models we use wouldn't anticipate the intentional driving in front of pedestrians by some drivers which is observed.
And as a final note, having read Donald Shoups book on parking, I have somewhat less faith in civil engineers' rigour than I had previously. My experience with some of the engineers at the region hasn't helped this opinion.
Given the low financial cost of converting to a scramble, and the ease of validating the important metrics, I'd argue a better option is to convert this intersection to a scramble for 2-3 years, and observe the outcome.
