Changing a faction in BI?

Is it possible to "modify" the western roman rebels faction? I want to make them playable and give them 1 region in Spain and see if I can rebuild the roman empire through them... I guess the real question is how do I make the towns that rebel against the Roman West turn into regular rebels and not the "Roman Western Rebels"?

i.e. just get rid of the shadowing bit for those two factions - then they'll act normally and you can add empire_west_rebels in as a playable faction in descr_strat and do what you want with them.

Thank You... It always seems that when I have a question, you have the answer!
