There was the character "Olympiad". It's not clear WHO Olympiad is though. But a lot of people think it's Diana. https://dc.fandom.com/wiki/Olympiad_...ndicate_Earth)Olympiad doesn't have wings. She has a cape, but not wings. also while she had a white skirt, the bulk of her costume looked like bronze.
The winged (alt-U Hawkgirl) character is Angelique: https://dc.fandom.com/wiki/Angelique...ndicate_Earth)
We don't see her much as she gets killed in the same firebomb that incinerates J'edd J'arkus(alt-U J'onn J'onzz).
Power Ring isn't an analogue of the Corps version of GL. He's seemingly an analogue of the Alan Scott GL.
