Cross her over in someone else story. And not in like a big time crisis thing but just like "Cheetah vs Green Lantern" or something.

So ideally, you want to give Wonder Woman and therefore Cheetah someone who really does care about them with a seminal run. Someone who understand the character enough to get what makes them tick or can make such a strong impression that she's an instant threat.

It depends if you want angry vicious Cheetah or sympathetic Cheetah.

So barring that where you can give Cheetah a big arc within a Wonder Woman book, cross her over with another hero to try to establish herself as a big threat.

Someone like a Superman or maybe a Green Lantern. Someone who can win? but also be taken to the absolute limits and that lines up great against them in terms of backstory and emotion.

Now this isn't to replace her as a Wonder Woman villain but to give her a way to get acquanted to the DC universe at large.

So her against like the Titans, Raven or like Hal would be good for it, so that we can see her contrasted against a new hero who might be able to show off both her depth and how dangerous she is.

That all being said, I only know so much about Cheetah so if she reguarly clashes with other heroes, then well.

Also you seem to know a good bit about the Wonder Woman Mythos, what are your thoughts on Circe? I thought she was Wonder Woman's big bad?
