Important question regarding factions and periods

Now this is a very complex question. I wonder if this can be done.

We have a problem with factions over at the Byzantium Total War mod. We have 21(including Senate which is the Papacy and the Rebels), but we want to add 2 more.

So, we create 3 periods: 976, 1204,1328.
I wonder if we can rename the factions when we advance to a new period. I mean, we have the Seldjuk's. In 1328, they become the Ottomans. Is it possible to do that?!

Also,
Because of the faction problem I want to rename the factions, and modify their starting position.(not in game).
I mean, we have the Cumans. They dissapeared before 1204, so I want to rename them and modify their position with the Kingdom of Kiev. Is it possible?! If yes, it clears very much our faction restriction problems.

Please reply, because it's very important.

Unfortunately, because of the way the data\text\ files are implemented by CA, the only way to do this is to have seperate installs for each campaign. You might want to check out the TFT mod (see my sig) for an idea of how we worked around multiple campaigns. We didn't specifically have more factions, but other stuff is different across each campaign.

Basically, we have a base mod with common files (the bulk of our download) and then seperate installers for each campaign.

You gave me a great idea. Thanks for telling me this.

Can we do the same?!!(we need your approval).

If not, I have a second idea.
