I dont suggest adding any other factions to the superfaction thingy ...

not that it makes much of an impact, but its ugly, very ugly
you start out with the other faction showing up as the others, they will stay so even when hostille later on (nothing diff. than with the others, but shouldnt be forgotten) you can not declare war on them (you can not attack them) but they will declare war on you by attacking you whenever your settlements are in the way (just like any other non-superfaction-faction) and will than give the message about the Jullii becoming outlawed (wich again can be rather confusing if they wouldnt have attacked you as you might actually think the Jullii gone mad ...:P)


so yeah, it does work, but no I wouldnt suggest using it ...
