+1 on the idea that if she needs that much saddle height, or even close to it, then you're not going to get there. She needs to sit on the bike with the saddle adjusted to her and then look at the stem situation. By using different angles of stems you can raise the bars somewhat but there's a limit. And as shown in that picture there's just no good way to raise the bars up that high. And neither should you since it would clearly be a bad frame fit by anyone's interpretation. Using strongly angled stems you'd be able to raise the bars about an inch and a half.

Before anyone jumps in and mentions that there are threadless steerer extensions available I'll say that they are a last resort and more appropriate to cruiser bikes for casual riding and have no proper place on a performance bicycle. If you find you can't alter the fit by only using the existing spacers and replacement angled stems then the frame is not even close to being a proper fit.
