weight could be 0.6 - 0.9 - trained for 768 (can have better results)
to keep close to her old design try any of these - or put in Neg to reduce chance - SFW/NSFW

face/body
RoboFortune, crop top, robot joints, yellow slit pupils, cat tail above buttocks, robot animal ears, underboob,
can replace crop top, with leotard, - can add belt pouch, or cat eyes,
tail is a solid color like her attire color
may need to specify outfit colors/not sure how flexible hair prompts are
her body is specific/ cat like - so some prompts like claws. etc may be useful and enhance her appearance
