As an archaeologist, Barbara may have read legends of the witch / sorceress Circe and those legends may have told of Circe's imprisonment. Barbara uses her many skills to find and free Circe, subject to Circe granting her the powers of a goddess. Circe, being a trickster and with all magic having a price to pay, grants Barbara's wish. But, the god-like powers of the Cheetah come at a cost, namely Barabara's mental health and ability to control her new wild and feral animal instincts.
The change would be permanent (i.e. Circe can't wave a hand and depower Cheetah). And Cheetah would be an equal to Circe, but in a different way (e.g. Circe "fights" by creating magical creatures to physically defend her, but Cheetah herself is a physical powerhouse).
I think it does somewhat neatly tie the characters together, somewhat fits their established characterisations and could help to establish an interesting interpersonal relationship between them. BUT, I don't think it is necessary. It is something I could see them doing in a movie - Circe as the more "intellectual" threat and Cheetah as her "muscle".
