Bloodlusted Diana is... pretty scary. She can fight completely blind without hinderance, power through any light-barriers put up, has no light-based abilities to steal, and either Dr. Light has been beaten by punching, which she'll do in a speed-rush.
She'll get burns and injuries but she'll beat either Dr. Light.
Also, is there any reason for the nudity? Or do you just like the imagine of Kimiyo fighting Diana naked? ^^
