There's basically 2 subfactions in Separatists, Droids and Geonosians (and 1 scoundrel, 1 NS, 1 sith). Since many people already have good geonosians due to the older geo ship meta, I'm betting that droids are the one CG has picked. Might be able to get away with a Poggle lead droid/geo team, or maybe even a Nute/Geo Spy team with heavy backup (Asajj, Sunfac, Grev), but unlikely you'll be able to get a 7* Padme with them.
