The ones that I would like to be (re)made are:
OT: a new Lando (in a new Cloud City, would be nice!), more tuskens!, a new Dengar and Bossk, Mon Mothma
Episode I: when do we finally get Boss Nass?, Schmi and an unfinished C-3PO, some new Kaadu creatures, Jedi Master Oppo Rancisis, Mas Amedda, Finis Valorum
Episode II: we really should be getting some Kaminoans, a couple of extra Jedi are always welcome, some CIS, Banking Clan and Techno Union figs (Lott Dod, Gume Saam, San Hill, Wat Tambor ...), a young Boba, again: Tuskens, Zam Wessel, Madame Jocasta Nu, and please, give us Bail Organa
Episode III: Tion Medon (from Utapau), lots lots lots of jedi!! (really need a remake of Aayla Secura), An idea might be a Wookiee/Kashyyyk set like the UCS Ewok Village (but smaller) and again: Bail Organa!
TCW: Lux Bonteri, Duchess Satine Kryze, Bo-Katan Kryze, Hondo Onnaka, Kalifa, Jinx, O'mer, Rush Clovis, Almec, Mother Talzin, Jedi Padawans (Petro, Katooni, Zatt, Byph, Gungi, Ganodi), Latts Razzi, Moralo Eval, Twazzi, Derrown, Queen Miraj Scintel, Sifo Dyas
Rebels: FULCRUM!! (PLEASE!), again: Bail Organa, Maketh Tua, Cikatro Vizago, Tseebo
