I have not seen that particular outcome, the main ones I've seen going around kind of contradict. Dany pretty much goes completely insane after routing Certs and Eurons forces, and burning everybody in sight, starting with Varys after she gets wind that he is plotting to back Jon, Jon kills her after being convinced by Tyrion it is the only way to save his family. Tyrion tries to free Jaime and Certs and ends up getting executed, or leading a post war council(like I said contradicting), Sandor and Gregor kill each other. Jaime kills Euron, and then him and Certs die together...just a lot of general stupidity. Jon either dies or ends up in the north(but I haven't heard anything about what you described)[spoiler/]
