Sorry if I just pop in, but I wanted to mention -if it hasn't be already- that it is fine to put the whole balkan together.
I know, there are still people who would be against it(due to history and bla), but actually we share everything together:
- location
- language
- culture
- religion
- food
and more.
We have just a few competitors, e.g. in croatia, serbia or bosnia, which just have like about 3~10 people in every country.
So I would see no reason why not to merge such rankings together.
I like your idea.
