Maybe for the shot where you see the maximum firepower lasers firing at the shield generator, making them green to indicate green is the strongest firepower as that laser is used for the Death Star, Star Destroyers, and the Tie Fighters
Ady has already said a long time ago the AT-AT lasers will remain red, so your wasting your time with the topic.
All Ady is going to do is brighten the laser cores and possibly add more thickness to the maxim firepower.
