If the goal of a jury is to be unbiased toward the person on trial (attempt equal representation from the citizenry), wouldn't biasing the selection now violate the right of the defendant to trial by jury of peers as much as the instance in question? We would do well to remember that the objective of jury selection is not to give all groups equal representation simply for the sake of fairness but to give the defendant a fair, unbiased jury for a trial.
It wouldn't be fair to today's defendants to do this, just as some sort of "justice" for those of yesterday.
