Alrighty, after a few days wait, I've got my "Villains and Scoundrels" setup done, so without further ado...
Scoundrels: Leebo (the droid from the 2010 Grievous Starfighter was the other choice for a head), Dash Rendar, The Mandalorian (Din Djarrin; until I get my hands on the AT-ST or Razor Crest this is the best I have for now), Cara Dune (same deal), Boba Fett

Imperial Foot Troops (I have multiple of each of these): Scout Trooper (Fallen Order-style), Stormtrooper, Flametrooper, Magmatrooper (based on Galaxy of Heroes model), Snowtrooper (I really want that skirt piece on the new ones)

Elite Imperials: Moff Gideon, Quirinius Phasma (the likely look of Phasma's father if he was in the Empire's stormtroopers), Two variants of Purge Troopers (Fallen Order), Purge Trooper (Uprising)

Imperial Brass: Lumiya, Imperial Doctor, Grand Admiral Thrawn (still looking for gold shoulder pads), Captain Pellaeon (I want J. Jonah's head but this one is good for a younger version)
