I think he definately would. Operate separately and phase out as fast as 737's could roll off the line. I really don't think he'd nuke his pilot group by giving anything even remotely close to a partial or greater relative integration to an extremely junior pilot group. GK and SWAPA would likely agree to a Guadalupe-on-Steroids arrangement to get what they wanted, and nothing more.

Also, however it went down, it would likely be a 2, 3 or even 4 party deal. There are things many other airlines would want out of something like that. With a certain amount of forced divesture being inevitable to some degree, might as well divvy things up on the front end while further reducing exposure to a relative windfall potential by a young group. Not every airline CEO would care much about that one element of a deal, but I'd bet GK would, and to some extent RA and DP too, if for no other reason than to grease the skids during the next phase of their master plan(s).
