All wiki bugs aside, your "may have" statements are automatically invalidated by canonicity. The 9DG are all from Zeref's library of works, as stated by a very reliable source, and the actions of the 9DG are ones of those who hate humans completely. Also, looking at his strength and personality, Silver is easily the strongest of the Gates and isn't someone who would be manipulated by the likes of Kyouka.
