I hope someone does, I'd love to see this expanded for the whole British Isles. I have a few ideas for improving England, but lack the ability to make any kind of functioning map.
I don't want to make a too large promise, but I'm working on a completely new map based on an actual map of the area displayed in CK. The map is working, but currently all of Europe + Levant is one province. I'm gradually drawing provinces on it, based on the CK map but with actual logical borders and new names.
It is far from complete though and will take at least a few more months for me to finish. Don't expect it to look particularly good either, I have zero graphical skills.
