Door Control? Maybe your LGS is different than mine, but I'd get screwed by Override if I ran any of those squads.
Cade + Palps can be fun for the infinite healing, but I'm not sure if it's really viable for 100 points. Maybe for 150 or 200. The old RS Palpatine and Sith Witches has been a fairly popular build for a long time. It's kind of cool to see it make a reappearance. The old version used RS Palps, 3 Sith Witches, and 3 Ugos, for 100 points even. So, if you went with 3 Ugs in your build, you'd have 7 points left. Maybe another Ug/MD and a Gran? Maybe 2 Imperial Dignitaries and 2 Ugos? Could do a Twi'lek BG and 2 Ugos.
The Arica/Palpatine one is cool too, but without Errata, it won't be as cool as it could be with Arica getting to use FPs twice per turn. I'd also go with perhaps a Storm Commando instead of the 2nd Sith Witch in that scenario. Gets you some door control, and another semi-decent shooter.
