Haven't played a Celtic faction yet...answer to this might influence which one I try when I get around to it.
Nope. I have only ever seen a federation in Spain between some 'Spanish' factions. As the Averni, I could only bring the people that run around modern day France into my Gallic Confederation. I suppose the same is true for British and Germanic.
