Nah, Blizz version of Kul'Tiras is lame. It looks like kultirans demote all their fleet to build those "houses". And the color palette of their buildings has a lot of similarities with goblin building from kezan.
I've expected to see something that looks more like Gilneas instead. But we get a mix of Kezan and Booty Bay that blizzard decided to call Kul'Tiras, the island nation of "humans".
On topic I can say only one thing: I can't see any profit in porting newer maps to old engine without all those new abilities they have in newer expansion, but if this kind of work makes you happy then I'll wait for ingame video with your results.
