Note about the Red Mage, he could have watered down versions of some of the Black and White mages jobs, and the Swordsmans jobs...but not all of them. With another 7 classes for each person then the red mage would have somewhere around 30 classes, and maybe some specific to him...so...we'd need to do something about him...maybe give him only a few of each persons classes and one or two of his own...
If, maybe, you could "pump out" a few example abilities for each character job (one or two would be enough - something like: Black Mage - Job: Elemental Mage - Fira, Firaga) then I'll be able to create a list of abilities and describe them so Aurvian can make them...
