I doubt it. If that was the case Yuna would not have needed to summon her aeons and would just need to kill the previous core ((SPOILER)Jecht). If Yuna never summoned he would have nothing to hide in and would have confronted them. If he was weak, that questions the logic of the final battles. If he was strong originally the logic works and the aeons were needed to weaken him sufficiently.
