I was actually going to ask you if there was any other purpose that you could come up with to reach out. IF you are determined to do this, that's how I would do it. Call her. Talk to her about the work stuff. Then follow up with... "we haven't talked much W. how the hell are ya?' ... something like that to open the door.
It's not ideal, but IMO, better than just calling her and laying into her with the convo.
