Callaghan will just be keeping the captain's chair warm until the real replacement is named.

... but the temporary aspect of the job limits choices.

Everyone seems to assume it's Marsch, but I don't know why they'd wait if that's the case.

That said, in the interim you get who you're gonna get. Hudson is a good guy and has been a model steward, but if got an opportunity no one should blame him for taking it. Nobody of note is going to want an incredibly temporary position.

Limited downside to it at this point.
