I don't think you can really divorce her from it and she still feel like Maxima and keep in mind her time on Earth would change her a bit. She wouldn't go back the way she came, so act 2 Max is probably going to enact changes in Almerac. Keep in mind I underlined that Almerac is problematic, but like Game of Thrones that doesn't mean it can't be fascinating. The story just can't get lost in the details. Moreover, the guys would be just as sexualized on Almerac. Hell, maybe more so.
My approach in many things is "own it, don't run, bargain or make excuses" so I'd rather embrace the problematic elements and make them work in a way that allows us to present a deeply flawed Maxima and tell a story where she hopefully comes out better at the end. Maybe she fails, but do remember that while not always on the side of the angels in Superman's story, she's the protagonist of Almerac's.
I think Ursa, Faora, Livewire and probably Silver Banshee are more prominent female Superman villains. Max went antihero pretty quick and died after like a decade. The others have been around longer and still get use.
Max has potential to be up there, though.
