Basically, the key is just get your stats up. You're doing it completely differently from how I did it, but I think it should work. Depending on your play style you might regret later on having Firion as a white mage. I'm not exactly an expert, but I've had Maria handling both schools of magic. Firion and Gus both act as the physical attackers.

I'm ridiculously overpowered, though, so your strategy might work better for a "normal" team.
