Editing fonts for nameplates?

[tomwearsglasses]

I've been working on cataloging all of the assets that affect the game's show presentation, and I've figured out how to edit most of them.  For the lower-third nameplates, I can change the animated graphics, but I'm trying to figure out how to replace (or at least choose) the font.

They each have a .pach file (within ltag_nameplate.pac).  Within those .pach files is a .dds file that appears to be the font set, but changing it doesn't actually seem to make a difference within the game.  

Each .pach also has an ATB0 and an FTPK file that I don't really know much about.  I'm wondering if there's a setting within one of those files that controls things like the font and screen position.  Does anyone have any experience with this?
