Have you considered using the Agartha connection with nagas of LA Patala? I understand Patala in particular was thought to be close to Tibet.

Have you given thought to sprites? Looking through the existing units and trying to find sprites that could be used with slight alteration can save you lots of time. Eric M has extracted all the sprites, and simple stuff such as recoloring or copying a weapon from another unit doesn't require much skill.
