Well, in addition to the clear cadian/valhallan/vehicle split, there are a few other models that don’t fall as obviously into either section!
At the moment, I think the painted sniper and ratlings are definites to add to the other Guard combinations for 135pts.
Painted Models (210pts)
Primaris Psyker (50pts or 75pts at mastery level 2)
6 Ratlings (60pts)
Special Weapons Squad (Old guard minis) – 3 Plasma guns 75pts
Unpainted Models (360pts)
Lord Commissar (Kapitan Ivanka Kurganova) – Power Weapon, Plasma Pistol – 95pts
