Can't say I like this idea since you'll have to get a specific gear (which will be difficult to get) then level it out.
I'd much rather they do it the old fashion way level up jobs (and increase lv cap) to get that skill. Better yet make gear (soldiery and dungeon) have at least 1 materia slot so that we can atleast have a degree of customization.
Better yet, make materia that increases proc rates, etc.
