[RMMV] YANFLY'S CHANGE CLASS CORE & FACE GRAPHICS

I'm using Yanfly's Change Class Core and would like to change the player's sprite and face graphics based on what class they are, but I also want to use the same face graphic in the message boxes (show text) for dialogue. I could use the 'show party member face graphic', but it would only use the basic one used in the menus. I want to keep using the facial expressions throughout the dialogue. I can't think of a way to get this to work properly. Any suggestions? Thanks!
