This is the kind of thing which can work well in the tabletop, with a human GM providing all the content and reactivity. I kinda think Larian has enough problems with getting reactivity to work as it is for all the existing backgrounds without adding in brand new "artificial limbs" backgrounds and personal questlines.
I’m going to be honest, this is a pretty weird thing to include and it’s probably not going to happen.
To be blunt, this.
