I'm almost wondering if, assuming Jack gets back to the past, Luffy might try and take him on alongside the rest of his crew. It'd be interesting to see a team effort like that post-timeskip, as the last one we got was fighting the Pacifista at Sabaody, which took literally everything the Straw Hats had at the time.
