Ireland, Wales, ect.?

[YankeeDoodle14]

I tried downloading the gaelickingdoms mod (which took several hours), but upon starting it I found that the game's interface had been significantly modified.

So my question is, is there any way to get the factions from Kingdoms (Ireland and Wales are the two I really want) to the vanilla Grand Campaign without altering the original game's layout by much?

Also, Norway.

Ne're mind, I got gaelickingdoms to work. It does keep crashing to the desktop though.
