This is essentially a mirrored mini-nosta, but the passage goes through the Treasury instead of the Guild of Outcasts.

Hmm... there are only 3 secondary zones there... there's no central zone, no Guild of Outcasts, and there are 6 Treasury zones instead of 3... and regarding "only a passage through the Treasury" - the structure of connections is the main thing in the template; the number and quality of zones are secondary. That is, h3dm1 even resembles Diamond more than Mini-Nosta.
