Jaina, Ben, Tahiri and Allana are the leads in the SotJ Trilogy - quite probably on a Sith hunt(!); which could be prolonged for however much time is needed. Another (possible) advantage is that current (Pre-Abeloth) canon puts the Order at a strength of 600 Masters and Knights + 400 Students (thank you, Sinrebirth, for providing those canon figures) -- and we have met (and/or had named) only an insignificant fraction of the Knights and Students. That said, Tirana Ki and Streen (little if any baggage to the pair of them) could make an Masters' appearance if set on Dathomir; but that would only be a nod to the existing EU, it doesn't actually need to happen. Dathomiri Witches, are known for wearing rather skimpy, animal hide. clothing -- and it would be great to see Rancors in their natural setting -- and being used as riding-animals/beasts of burden! Somewhere in the Hapes Consortium is another possibility -- lots of very beautiful ladies (it's a Hapan cultural trait) to be interacted with/in background shots. Tennel Ka (Hapan Queen) needn't appear, she's probably too busy with Affairs of State and keeping backstabbing (literally) Hapan politics subdued.
