As far as revamps go, this is for anyone who watched Wonder Woman 1984 and a classic villain was mentioned. I'm not sure if it's okay to mention publicly so I'm putting it in spoiler tabs:

What do you think of revamping Duke of Deception of a reality warper who grants wishes to cause chaos. He can still be an agent of Ares, and he would have a legitimate reason to target Diana and her friends. Make him an extremely handsome and charming man who is constantly trying to trick people into wishing for things in their worst interests.
