This would be very cool, and fairly intuitive! I know they're planning some kind of "saved actions per job" palette of some variety, Yoshida's mentioned it more than once, but I know I'd prefer to have multiple action palettes saved per job, and multiple gear palettes saved in general. The Armory system was sold on the strength of switching from job to job on the fly in the field without screwing about with actions and gear and so on; this would go a long way towards fulfilling that design premise.
