Unfortunately, as you are aware, as she is sold, she is not rigged.
Why they would do that, well you would have to ask the vendor about it?
How much work there is in making her into a usable character, I don't honestly know.
You will have to wait for the input from someone knowledgeable in that area.
That said, I would put in my usual 500 points for her as a proper usable G8.1F character.
this is just a 3D scan, there's no easy way to make a G8/9 character out of her. means a lot of tedious manual work for days ... good luck to find someone who is willing to punish himself 😄
