Okay, I've been hashing and using the textures given. So I want to post progress and whatnot.
So Mcindus, I've been using your test map and went around everywhere to gather the codes. Not sure if this is all of them(or if you already found them all) but here they are if you or anyone else needs them. This way the maps don't disappear anymore.

Second, after creating my own dummy low poly characters from Mago's textures, I believe I've found almost all the hash codes for every character...except Edea. Of course, some of these cause glitches... Like things going invisible. Not sure how to fix that.
And here are some pictures of other things...because why not?
Seifer, in your first battle against him.
Squall with bandages(because I wanted to test out the code).
And Devina's Squall in battle. ...Just because I really like it.
