And since Athena is usually one of Diana's main patrons, it adds for some interesting potential plots about what constitutes justice and judgment.
Giganta - just have her be a freakin' gorilla who was evolved into a woman. It's what Marston did with her, and that campy absurdity works best when embracing it. If that's out of the question, then just have her be a big buff woman who can grow and works as a mercenary. You don't need to have some grandiose origin or motivation for this iconic character.
Diana - I'd revise her origin back to her original one to cut the stain of Zeus out of her. She doesn't need a dad, dude.
