Try a Moustache bar such as Soma Moustache 2. Don't forget to use some ergonomic hand grips and angle them so that her wrists are straight when she rides.
She would need to size up or get a more comfort oriented bike if she wishes to be any more upright than that. I'd start by at least ensuring that saddle is level and getting rid of those awful bars if getting a different bike is out of the question at this point.
