Would need to include new melee animations. Simple claw slash (with both hands alternating) as a basic melee attack and a leap thrust animation into the neck super move, with the same trigger as the mantis blade impalement move. Maybe a rolling midair leap skill that lets you temporarily dodge bullets? She was basically dodging point blank shots from that robot in midair.
Sasha looks really good in the music video so I think it would be awesome. Also, a cat fall cyberware that lets you survive a fall from height once with a long cooldown would also be great. Sasha survived her fall though she probably got knocked out. No bleeding or visible damage or deformation to her body. I imagine she's just in hiding from Biotechnica so she doesn't show up in the anime. Please make an awesome DLC questline for her. That music video was too awesome to not have an in-game follow up. I'm thinking a chain of missions with different fixers as she dodges biotechnica throughout the city. Maybe she winds up in hiding with the Aldecadoes and cameos in Panam's ending sequence. New romance option??? Oh, the possibilities...
