Mog's Battle Hud EX - Changing Avatar Faces Mid-Game [ACE]

Good afternoon! I am having bit of trouble with figuring out how to do what I am intending with Moghunter's Battle Hud EX script. I have placed all of the files in the proper folders, everything is working fine, etc... However, my main character goes through a few transitions during the game and has forced class changes, which also include a change in character portrait.
 
I am wondering if there is a way to script the change of character portrait to update the Battle Hud face selection as well? For example, Avatar is Class 1 at beginning of game with Face A. I have that face.png in the Hud/Battle folder and it displays properly. At a certain point in the game, I have an event that changes the Avatar's class and his portrait and I would like to update the battle hud face as well, to match.

Also, I tried doing the naming convention in the script... IE CharacterName_Face.png and it doesn't seem to load... Also tried Face_CharacterName.png without any change. Face_1.png and Face_2.png seems to work, however. Perhaps using seperate actors and swapping them out might work, assuming the # value is referring to the actor number in the database and not the party order.

 
Any thoughts or insight? I've included a link to the script below.
