Perez's Cheetah is a strong concept, but I wonder if it wouldn't have fared better on a brand new character intead of grafted onto a pre-existing one. Cheetahs are so strongly associated with speed that high levels in other superpowers comes off as counter-intuitive. Plus, she's a were-person, which in superhero comics pretty much always have very low-level super-strength, nothing close to Perez's Cheetah's level. The pre- and post-Crisis versions of the character already have next to nothing in common, so it's not like it would've been much of a leap.
