Are you planning on giving Orcs of the Misty Mountains the Gundabad spear-version Goblin Band, and Gundabad the Misty Mountain sword version Goblin Infantry?
I ask because in my campaign using 1.3, each side has a number of Goblin Infantry with the Rome Peasant UI card and a textureless battle model. I figured you were filling out their roster a bit but it had a few bugs along the way.
