The ISIS apocalypse covers your question, along with OP's history in more detail. Very easy read, and very informative.

ISIS split from AQ before the death of bin Laden. AQ and ISIS had disagreements before bin Laden's death, and the emails / notes of those arguments are part of the book I linked. They're basically separate organizations which cooperated when circumstances warranted. I'd be surprised if a new bin Laden could unite them because bin Laden never led ISIS, but I'm not an expert.
