No sir, let her move on.
I said this once or twice here but I only want her to mimic two different animals Gorilla Grodd (she done already) and Krypto the Superdog (she was able to mimic Superman, so he should be within her power range).
With Gorilla Grodd - She would gains his genius-level mind, enhanced durability and strength. She would also possess his many telepathic abilities, enabling her to read minds, communicate mentally with others over long distances, stun the minds of others with "mental bolts," control the minds of others, and create illusions in the minds of others. Vixen would also become a powerful telekinetic, who can use telekinesis to lift and move objects (including himself) with only her mind. She could levitate and fly at high speeds, and can carry many people while doing so. She can form powerful psychokinetic force fields or use her telekinesis for concussive blasts. Grodd/Vixen's mental powers are so powerful they could even work on the molecular level of things
With Krypto - Vixen gains all of the classic Kryptonian powers: super strength (easily falling Marvel's Class 100+ strength level); flight (near light-speed); super speed (again near light-speed); invulnerability (on Superman's level); x-ray, telescopic, microscopic and heat vision; freeze breath; and super-hearing (greater then Superman).
