Factions and cultures

[Agraes]

Well, for my mod Arthurian : Total War I need to have 20 factions in 5 cultures. How I could do that ?

BRITON CULTURE (ROMAN)
Dyfneint : WRE
Dyfed : ERE
Gwent : WRE Rebels
Llydaw : ERE Rebels
Alcluyd : Goths
Rheged : RomanoBritish
Gododdin : Ostrogoths
Powys : Slavs
Gwynedd :
Ynis Manaw : Berbers
Elmet : Sarmatians
Ebrauc : Roxolani

FRANKISH CULTURE (NOMAD)
Franks : Franks

PICTISH CULTURE (EASTERN)
Fibb : Celts

SAXON CULTURE (BARBARIAN)
Saxons : Saxons
Juts : Burgonds
Angles : Alamans

GAEL CULTURE (CARTHAGINIAN)
Ui Neill : Huns
Dal Riada : Lombards
Mumainha : Sassanids

Is it possible ? I know how to change faction name, but when I replace a faction culture in descr_sm_factions I got a CTD.

Also, can someone tell me how to make playable and 'normal' civs for the Roman Rebels, Ostrogoths, RB and Slavs ?

it should work, I have replaced cultures several times, and it has worked...

And for the others, you have to remove all spwan_on_event, spawn_on_revolt and that, form descr_strat and sm_factions....
