Okay. So, if the new file size is due to missing textures from JO, how hard would it be to create a
new Sublime specifically for JA (copy it to a new file) and call Academy textures in places where JO textures are called for in the original? Or would that take years?
(I don't map, so these are rhetorical questions.)
Naturally, if too many textures are missing, it's an incredibly lousy idea. Call me crazy. But, if it's only here and there, it might prove an interesting change of pace between games. (You haven't said which textures are missing. Is it actually 14.25 MB worth?)
There are quite a few interesting textures in JA that seem to fit the feel of Sublime very well. I can imagine a slight color shift from that soothing green to a just-as-soothing blue or dull gold in places, judging by the JA maps I've seen so far. But personally, I don't think I'd miss any of the textures from Lando's ship, for example. And the "blue room" is actually more on the gray side in the JO version for me. A little more color there would be a great point of interest between the respective versions.
New game; new map. Something along the lines of "Serenity" might be a good name for it. Seems to invoke that feeling, anyway.
