My idea about a mod based on the Forgotten Empires

I feel that there're too many civs in the DLC version and many of them aren't distinct enough. Here's my proposal for a mod based on the Forgotten Empires, with some new civs added. Here're a list of the civs in this mod (with the new civs and their the unique units highlighted in bold letters):

Annamese

UU1: Elephant Skirmisher UU2: Mong Dong

Aztecs

Britons

Byzantines

Celts

Chinese

Franks

Goths

Huns

Incas

Indians

Iroquois

UU1: Tomahawk (functions as their scout) UU2: Mantlet

Italians

Japanese

Khazars

UU1: Arsiyah UU2: Kabarian Cavalry

Khmers

UU1: Ballista Elephant UU2: Jungle Skirmisher

Koreans

Magyars

Malays

UU1: Blowgunner UU2: Djong

Mapuches

UU1: Mapuche Lancer (functons as their scout) UU2: Ironwood Club

Mayans

Mongols

Nubians

UU1: Nubian Archer UU2: Camel Skirmisher

Persians

Polynesians

UU1: Maori Warrior (functions as their scout) UU2: Ula UU3: Pahi

Saracens

Siamese

UU1: Temple Guard UU2: Siege Elephant

Slavs

South Chinese

UU1: Zhanmadao UU2: Bamboo Firelancer

Spanish

Tanguts

UU1: Camel Slinger UU2: Tibetan Mastiff

Teutons

Turks

Vikings

In addition, each civ gets a tech called Mercenary in the Barracks at the Castle Age; after researching it they can unlock their regional specific unit (Except Mongols, Tanguts, Huns, Turks, Khazars, Iroquois, and Polynesians).

All European civs (Britons, Byzantines, Celts, Franks, Goths, Italians, Magyars, Slavs, Spanish, Teutons, and Vikings) get the Norse Axman

All Middle-Eastern civs (Saracens, Persians, and Indians) get the Hashashin

All Northeast Asian civs (Chinese, Japanese, and Koreans) get the Warrior Monk

All Southeast Asian civs (South Chinese, Siamese, Annamese, Khmer, and Malays) get the Rattan Warrior

All Meso-American civs (Aztecs and Mayans) get the Coyote Runner

All South American civs (Incas and Mapuches) get the Bolas

Iroquois and Polynesians don't have access to this tech.

Mongols, Huns, Turks, Tanguts, and Khazars get a regional specific unit called the Eastern Cataphract in their Stable once they reached the Castle Age. They don't need to research any tech to get it. It has similar stats as the Byzantine cataphract and it does trample damage against infantry, but it has 1 range similar to the Steppe Lancers in the DE.

Feel free to share your thoughts about my plan.
