Alright, I've found a guide to mod out the Senate, I've also learned to "unite" the Roman houses under one banner, and even found a guide how to give Families Unit Surnames, but that is about where my knowledge stops. In my mod, I want to "transform" the Julii into a new SPQR Faction, and by that I just mean to have them use the SPQR Colors, Banners, Buttons, those thinks. I want them to LOOK like the old SPQR.

So, what I need to know, is it Possible, if it is, can someone give me a step-by-step guide to how I do it?
