Not successfully ><. I could swap the audio for Sublimation, but not for the stratagems (when you open it in a hex editor, there's a lot more information there, so I'm not sure where the audio information ends). But, I only really tested it in AltanaViewer. Swapping the particle effects is beyond my abilities.
For now, I've got an empty file instead of the original dats, but that works to some extent. If anyone nearby is casting a spell at the same time I use any of my blanked out JAs, I will use the animation of whatever they're casting (eg. when someone casts Thun4, it looks like I just casted Thun4 on myself).
