I don't think it's the map itself he's saying melds the two, it's the idea that like oldschool FR the book is filled with little adventure ideas and rumors in various locations in the FR all sandbox like.
Yes indeed. Thread title aside, I think the first chapter in the FRCG is (to iterate myself) "closer to the spirit of an OSR setting than the proponents or detractors of that movement might care to admit".
On-topic, I really like what the OP has done with the map. I tried to do something similar with a hex mapping problem I found online but my map-fu is sadly lacking. If you use the regional map from Sceptre Tower of Spellgard there are some additional sites that would be perfect for expanding the area further into an old school sandbox.
My copy of that module arrived an hour ago in the mail.
I've updated my OP with suggestions where to place these adventure sites. They really are suggestions - as pointed out above, some of the terrain adjustments on my map from forest to mountains and vice versa, call for the creative "placement" of some sites. - For those not caring to click back onto page 1 of the thread, here are the updates:
