The scenario is skewed towards the Destiny universe. It's Light+ Darkness + everything. You know that will not happen unless morals are off for the Destiny Universe team. They will never team up. Same thing with Goku. He will not just blow things up because he is good hearted. With morals off for both sides, Goku will win a long war. He will make clones of himself and fight as a team. He can make enough clones of himself, observe the mechanics, and figure things out. In an all out war with morals off for both sides, Goku stands a good chance to annihilate the entire Destiny universe.
