Sixth Brother started as a spare 3rd Sister figure and added a skirt cut off Fin figure. Added spare lightsaber from 3rd sister and cloak from Jyn Erso (Jedha).

Seventh Sister started as spare 2nd Sister figure and added a custom 7th Sister head (which I copied and molded in black resin). Added a skirt from some other figure (don't remember from where). Finally, I copied an Inquisitor lightsaber (with red transparent pieces bought in bulk) and painted a custom head purchased online.

Eighth Brother was a 3D printed set of armor purchased off Etsy. Used an Iron Spider figure as the base. It looked sufficiently lanky and long-limbed to almost fit inside the armor. Trimmed off large sections of the forearms, lower legs and chest/back area with a utility razor knife (Slowwwly and carefully. Have cut myself too many times before with these dangerous things!). The torso armor still didn't fit together completely so had to finish it off with some Apoxie sculpting clay and of course a nice paint-job.

Ninth Brother started as a Finn (First Order Disguise) figure. Added a copied Inquisitor Lightsaber and the final touch was to add ammunition pieces from a 3.75" scale Death Trooper's utility belt to his chest (to cover up the obvious Imperial Office code cylinders on his chest).
