Given that Louisoix gave the twins the books and said the true knowledge within would be unlocked when they used them together, I could possibly see a Blue Mage connection, but the sudden and drastic shift in class/job for Alphinaud would seem strange and maybe a little forced. Especially as Hoary Boulder has given us plenty of teasers about Blue Mage in his own training when he was off.
That and I'm not sure Blue Mage would suit Alphinaud. We don't know what the class is yet, but a long-ranged caster placing aether constructs between himself and harm's way certainly seems to fit Alphinaud as a character. He's a strategist, a chess master. Blue Mage would necessitate putting one's self in harms way just to learn.
