Living FR had a handful of 4E adventures (really one story arc) set on Laerakond. I had fun emphasizing the cultural differences.
"You say you are a 'cleric'? The gods are dead, man; the dragon lords ate them."
"What is an 'elf'?"
While it could be interesting, it would be a low priority. I'd rather it be explored peripherally, perhaps as part of an adventure in the FR that takes the PCs to it for a limited time.
