Good mod for individual Kingdoms Campaigns?

I've been playing the "Grand Campaign" using SS-6.1. I've never tried the individual Kingdoms campaigns such as Brittania, The Crusades, etc. Any mods for them that improve gameplay and are compatable with SS for them?? After playing the Grand Campaign with SS, I'm spoiled! Don't want to go back to Vanilla.

Ideally, I'd love to play the smaller Kingdoms campaigns with the same or similar gameplay changes that SS brought to the big campaign, but any improvement on vanilla would be ok. If there's a SIMPLE way to transfer as many of the SS changes to the small campaigns, that would be great!

Thanks
