I'm willing to bet that it may not stop Kenny at all. He will steal the serum, inject it in himself, eat Eren and possibly kill both Rod and Historia. Maybe there was a reason why Kenny was waiting to try to get rid of the Reiss Family and instill himself as king. Maybe he and Mikasa's father were involved in a failed revolt against Rod and the Ackerman families got persecuted. Mr. Ackerman escaped persecution by running to the forests, while Kenny hid underground avoiding the Military Police and training Levi as well as the female who looks like Annie(but isn't). The only reason why Rod was willing to spare Kenny in exchange for his services was because the Ackerman's supernatural abilities are well known to him.
