Do the models and textures first, then ask for adding them.
No need for models, just textures and a bit of messing with other files to get the game to load the heraldry properly. This takes effort, however (though admittedly not a whole lot), and with the dev's tendency to completely ignore 99% of the threads in this forum, it would likely go to waste. Zagibu actually DID make some of these, but they weren't added. Honestly they could have used a little work, but 5 minutes on photoshop and they would have been fine.
Sadly, devs said no and people bitched and complained over nothing.
