Is there perhaps anyone whom knows the inner workings of Independent Arcutecture + Independent Units, that can expand on the divercity of the current civ unit divisions?

Saint Michale did a superb job to split the factions into Europeans,Middle Eastern, Asian, Bysantine, Japanese and New world civs. It improves the game completely and captivates you intensely.
As wonderful as that division is ,I, for one, hate fighting as Britons against the Vikings and have the Viking units look exactly like my British units.

I need someone whom can split the civ divisions further, that will allow me to create unique slp's for even more historically accurate civ diversity.

This is the divisions in the Civilisations that is required:

Western Christian Europeans - British, Franks
Clets
Catholic Europeans - Italians, Spanish, Tutons, (Portuguese if not separate)
Portuguese
Slavs
Magyars
Barbarous Europeans - Vikings, Goths

Barbarous Asians - Mongols , Huns
Central Asians - China, Korea
Japanese
South East Asia - Burma,Khmer,Vietnamese
Indians

African - Ethiopians, Mallians,

Byzantines
Middle Eastern civs - Saracens, Berbers, Turks
Persians

New World

If anynone can aid me in achieving this, please let me know. I will be most gratefull.
