Completely different ideas: She manifests her aura into a pseudo arm for fights/she gets a new arm but it's not a mechanical but like how Shirou has Archer's arm transplanted in Heaven's Feel and more beastly.

More orthodox ideas like how Ironwood and Merc have robo prosthetics: Piston action bionic arm to pack more punch or stretchy and extendable for reach.

Personally I wouldn't mind if she doesn't get one and proves to be a badass regardless but not going to happen.
