If there was an (unique) upgrade card to increase the greens by 1 to 3,
even Rhymer would be worth to take (with Prockets):
(unique) Enhanced Turbo Thrusters
Modification, Tie Bomber only

"Increase your agility value by 1. You cannot equip this card if your pilot skill is "6" or lower."
So I don't think that existing cards have to be reprinted with different values - there are different ways to make unused pilots and upgrade cards usable.
