I mean, I know, God forbid, it gives Diana seniority over the other members of the Trinity, but it does less damage to the character. (The other solution, depending on whether you prefer "Golden Age Wondy" as a concept or "Hippolyta is a badass", would be to send Polly back but not as Wonder Woman - call her "Amazon" or something, and say she ended up so busy fighting Nazis she never got a chance to tell anyone who she was or where she was from. It still guts the mythos a little, but it's a better solution than having her be Wonder Woman.)
