Well, I just found the only mod that tries to fix their map, which's Calradia Expanded - haven't tested it because it's currently discontinued due to the creators throwing a tantrum at the game getting patched
But one can roll-back a few patches and fiddle with it, I know I wouldn't though.
The fact's that I believe that BL's map needs a "total makeover" to fix balance + place the proper settlements in their proper zones with their proper names. This mod does some of it but at the same time makes some questionable decisions with "creative liberty", but at least it's a "start"
