Barbarian Invasion - Rule Discussion

[Boron]

I had the idea for a special Scenario MP game.
In the Alliance vs. the Dead thread i suggested it already:
Thread

The base concept of the game is that it will be roughly a fantasy Barbarian Invasion.

2 players will be allied and play Western and Eastern Roman Empire, the other players will also be allied and play the Barbarian Invaders.

Settings:
-Most recent CB Mod, 5.2 or newer.
-Zen's Europe Map
- 6-8 Players

If you are interested post and then suggest/vote for my suggestions open for discussion which i will post now:

1. Roman Nations
suggest 2 Nations
2. Barbarian Nations
suggest up to 6 Nations
3. Should conquering the sea provinces be allowed?
a) yes
b) no
4. Victory Conditions for the Romans
