I suppose they could line it up to where it'd work for a special week. I mean it's not like they haven't aired movies before and some long finale eps like FLCL's or Hellsing's, so maybe they could do it as a special night since it'd just be for that last week.
Cool, I enjoyed it. Even with some of the differences like the younger versions, it still feels quite familiar so you should feel mostly right at home having seen the other stuff, like SAC. It's also quite neat seeing a younger Motoko and Aramaki get started and bring in the team.
