Just for the sake of first impressions, I'll jot some notes down on a Cimmerian/Thracian Middle Era, based on your database:

First of all, it will feature a large amount of berserkers, who themselves will be better equipped than the "average" berserker unit, and several stealthy units. I'll also decide, for thematic reasons, that the Ordes are somehow related, or atleast similar, to the Van, and give them a Capital only Glamour unit. They'll be the only non-human recruit, and won't be sacred.

Doryphoro-Dacian militia, armed with spear, round shield, javelins.
Triballoi-well equipped berserkers, armed with longsword, javelins, round shield, leather armour.
Pelekuphoroi-bushwhackers, armed with bronze axe, scalemail, round shield. Stealthy (5)
Epilektoi-elite melee, armed with studded leather, longsword, javelins, Thracian helmet.

Prodromoi-Medium calvalry armed with light lance, round shield, sica.
Pylakes Daoi-mounted berserkers (I don't think we've seen mounted berserkers before, in the game)
Hippotoxotai-Elite Horse-archers armed with shortsword, composite bow. Unarmoured. 16 morale, berserk (0), Stealth (0)

Komatai-Sacred, armed with large shield, leather armour, javelins, and a sica, which will do 3 damage, and be armour-piercing. Stealth (0). No helmet.
Drapanai-Sacred, Berserk (2), armed with the Falx, which will be armour-piercing, and do 6 points of damage. No armour.
Rhomphaiaphoroi-Sacred, equipped with the two-handed Rhomphaia, plus a small shield, and a full suit of chainmail. The Rhomphaia will be armour-piercing, and do fully 9 points of damage.
Absolutely elite human soldiers, close to the Emerald Guard in terms of stats. Lots and lots of resources for these guys, though.

Sphendonetai-Slingers with small shields and shortswords.
Toxotai-Archers armed with composite bow, spear, 12 Morale, and Stealth (5)
Agrianai-Elite archers, armed with composite bow, studded leather, and longsword. Prec 11. Morale 13. Stealth (5)

Ktistai-Capital Only, Calvalry, Sacred, armed with composite bow, falx, chainmail, Thracian helmet.
Ischyroi Orditon-Capital Only, Glamour, Stealth (0), armed with sica, chainmail, Thracian helmet

Now ofcourse, these could all change a lot, in creating a mod, but it's a good basis for an original human Middle Era Nation, I think.
