I don't regard those women as Orion. The Orions we've seen have skin a different shade and black hair. They were, quite frankly, much sexier than the Christmas colored cuties in NuTrek. Why can't they be another greened-skin people? There are enough brown- and beige-skinned humanoids in Trek and at least two prominent blue-skinned races in the Andorians and the Bolians. Maybe these girls were the vaguely Vulcanoid Rigelians we heard about JtB.
