Old World of Iron: Border Princes pt. 2 and the Borderlands

So I just had an interesting idea about the Border Princes, and I think this is how I'm going to pursue them.

I'm going to basically do an older version that I had considered in the past, previously titled the Marcher Baronies but now called the Borderlands. The Borderlands will, in fact, be very similar to the Border Princes but with a few caveats. For example, there are established kingdoms in the Borderlands - not many, but they are there. Further, the Borderlands will basically combined the Border Princes and the Badlands into one thing - parts of the Borderlands will also be inhabited by goblinoids come over from the Land of Darkness (a new area I'm going to detail), but I'm not going to delineate it into south v. north.

Where does that leave Osmanli? In relatively the same place, but I'm going to move it west to where Warhammer has Araby. This will also fill out my desire to kind of do the whole Mediterranean region. My not-Egypt isn't going to get a region, as I do not really want a Tomb Kings analogue - they will instead be one of the many kingdoms that has risen and fallen in the Borderlands. Basically, the Borderlands will be more SE Europe than purely the Balkans
