I agree, I think giving every good guy a keyblade a bit much. I think it is cool if they all had their own weapons, and honestly, I always thought Axel's discs were one of the coolest weapons on the orgs. behalf so I think it would be kind of boring if Nomura became Oprah: "You get a keyblade, and YOU get a keyblade, and YOU GET a keyblade, YOU ALL GET KEYBLADES!!!!"
If any character from FF Type-0 gets in the game, I'd hope it is the Cranberry Knights.
But sneaky and conniving was the attitude that made him so appealing to many people, and made his character so favorable. He can be changed, but I personally hope he retains some of his attitude.
