Common Colour Balance with US sheets

WoTC could have maximised variance and achieved 100% packs with all five common colours (treating the lands as the colour they produce) with their existing print sheets if they had instead used the following structure for collating commons.

AAAAABBCCDD
AABBBBBCCDD
AABBBCCCCCD
AAABBCDDDDD

Alert - this is not how the real packets are, just what I thought they should have done.
