I think Yoshi-P mentioned in a past Q&A session that they'd look into the armor since the Garleans are no longer enemies.

That said, signed the petition. I'm definitely a fan of making this all happen.

Honestly, I think that the gunblades (or at least Heirsbane, Gauis' weapon) could be done like the Blackbosom Scythes - use them as level 1 glam items for each job that could reasonably use it in animation. It's not a true gunblade, but it's an illusion (and honestly, if I was a Resistance Gunbreaker outside of Bozja, I could see myself glamming my real Gunblade to blend in on infiltration missions) so it wouldn't matter. Then you could use it for Paladin, Gunbreaker, possibly Samurai, and even Red Mage (DRK probably should get the one used by the enemy in the GNB story quests, or perhaps Regula's). Actually, add machinist to the list for Heirsbane - it's still a gun.
