We haven't modeled new hair per se in the character creation, but Kuauik has done a fantastic curly beard & hair & fillet (headband) for the Immortal/Apple-bearers dress, so it might be possible to do in the future. We would be interested if anyone is able to do editing with hair or beards, though.
And thank you rgcotl. As you note, doing a faction really is exhaustive work and it's not something we approach frivolously. One has to design a roster, chart out settlements, create scenes for them (very exhaustive work), provide for lords and ladies of the faction, create models and textures for them, equip them, stat them, balance their party replenishment/reinforcement rates. The fact that we are still doing this for our current factions shows how far from our mind doing even more factions are. I am sure post release we'll consider them.
You can recruit Ahlamu mercenaries and fight Ahlamu banditry (Among the dizzying array of either), the term being one of the generalized Akkadian words for nomads/bedouin/desert folk, used in our case to describe Aramaeans, Amorites, Qedarite Arabs and any other group of people inhabiting the desert regions of the fertile crescent. But aside of using the camel you cannot expect for them to be the iconic pre-islamic kaftan wearing bedouin. These are Bronze Age bedouin of a different flavor - light, unarmored skirmishers with slings, javelins, bows, spears, some swords or axes, and some camelry.
