I understand, yeah she would be applying for a tourist visa but once if she applies for a PMV wouldn't she go on a bridging visa. The only drawback to that is she wouldn't have working rights till she gets the PMV.

I may be totally wrong here

In addition to what they've already said above, assuming she could apply for an 820/801 from a tourist visa without the "no further stay" condition, she would be granted a bridging visa A. The BVA kicks in one the tourist visa stay period expires, and then she would have work rights once the BVA was active.
