Final Fantasy Hacktics

So, to begin, "Hi! I'm new!" Now that that is out of the way, I could use some help. I'm a big fan of the Ivalice Alliance games ion general, but the one I hold closest to my heart is Tactics A2.  In-game, there is a boss called Oversoul who appears in one of the storyline missions (I believe it's Sleepless Nights). What I want to know is this: is there a way to take the animation from when it spawns (1:30-1:39) and when it leaves (7:30-7:41) and, whether with the hacking tools or through pain and arduation hex code programming the old fashioned way, program an attack(s) to use one and/or both animations?

Thanks in advance.
