A new die type is not a bad idea per se. I do wonder with Imperial Assault and Armada coming out, if in hindsight the developers would have done a secondary weapon die? Green for defense. Red for primary. Blue (or other colour) for secondary attacks.
While this could be implememted, it is as tricky as changing the core rules in the faq. If a second edition of x-wing came out, I could see it then.
