Swapping factions

[Stuie]

I don't know if this would work, but in the descr_strat.txt file, you could look at the line which says

faction romans_julii, balanced smith

and change that. This would give them exactly the same units and characters and family tree. It might cause the game to crash, but it might also work.

If you took this approach, you would also have to change the faction ownership in the export_descr_unit.txt file for all the units involved. Otherwise the game would crash.

EDIT: And you'd have to change the export_descr_buildings.txt file to allow the correct factions to recruit the correct units.
