14 teams? Which ones would that be?
Obviously, Maribor has contacted EBEL recently. Innsbruck and Feldkirch could possibly join EBEL (again) in the future. With the italian teams it is a bit more complicated. Either you take 3-4 (Bozen/Bolzano, Val Pusteria, Cortina, Asiago?) of them or none. EBEL would have loved Bozen/Bolzano Foxes to join, but the italian hockey federation rejected the proposal and so Bozen/Bolzano had to stay in Italy. FISG and LIHG would not let their most famous and attractive team go, as this could turn out to be a tremendous weaking of the Italian Seria A's attraction itself.
At the end of the day no one really knows what the future will bring regarding the expansion of EBEL, but one thing seems to be very unlikely: A Polish team joining EBEL -> that just would't work
