Sounds like President for Hockey in Serbia, Marko Milovanovic is trying to create plans to make a domestic league spanning across Balkan's including Croatia, Serbia, and Slovenia like Austria's EBEL league. As of now it's just an idea and no plans if expansion includes Bosnia & Herz, Romania, Hungary, Bulgaria, Macedonia, or Montenegro..but definitely interesting to hear about if it happens in the future.

But for Milovanovic the future lies closer to home. He wants to see the Balkan nations form a joint league.
“We need to develop a league in the Balkans, maybe with Serbia, Croatia and Slovenia,†he said. “I think that’s something all these countries need as a strong domestic league.†~ Milovanovic
