Well there's a ep with basically a evil Amazon named Aresia
https://dcau.fandom.com/wiki/Aresia
What about a idea like the one we discuss but she's the one who does
it and babys Wonder Woman as part of a new play or something like maybe she makes herself the new Wonder Woman and Diana is forced to be her baby sidekick
Or something with Hawkgril babying Wonder woman since there was a time they didn't get along.
If not we can do the wonder girl one I just thought I'd mention those
