I doubt a semi-shoehorned in prequel ship would be the one to have revoluntionary mechanics. It'd be more like a slower, slighty tougher X-wing (assuming in date tech.)
I suspect that's just your dislike for the ship speaking, FFG will do whatever fits, both thematically and in gameplay. Besides, it's nothing new, really - we already have rear arcs, ships that can fire their primary and secondary weapons in one turn and upgrades unique to one ship, it's just a new combination of existing ideas. Like most ideas are, in fact.
