I thought that was interesting too, but yes, that's the same thought I have as well. Plus, we'd still be left with a loose thread: since it turns out he's obviously an Imperial agent in that scenario, does he ever get what's coming? That will remain something difficult to resolve.
Interesting idea to let Boba run the criminal empire. Could be a decent way to part ways with him and simply leave him out of the rest of the story. Could you maybe give a rough mockup to show us how it could work? I could see using the Boba footage when he prepares to shoot Leia (as Boushh).
