I would want Lex Luthor and Brainiac to be in MOS2 and finally be in a Superman film period. Luthor would work as he could fit the plot for MOS2 for whatever role he is (President, scientist for hire, etc.). And Brainiac; well, when MOS was first brought up, tying into Nolan producing making the news, the villains were said to be Luthor and Brainiac until the announcement of Zod seem to debunk that. Later on though, it was rumored that Brainiac will be either seen, mentioned, or hinted as the reason for Krypton being destroyed. We don't know if its true or in the final product. Though, if he isn't in MOS but in MOS2, then I can imagine that Luthor creating Brainiac and Earth being hit from within would sound like how they would approach Brainiac. But/plus, after Zod's alien invasion, they would need something different as not to repeat what they did.
Either way, both characters would work for MOS2. But an alternate idea would be to have Luthor in MOS2 and Brainiac for MOS3, and the other villains in MOS2 would be Earth's countermeasures against Superman, which in turn is/akin to the Superman Revenge Squad (Metallo, Parasite, Bizarro maybe etc.) which could double as Luthor's secret plan to BE Superman himself (like his story in 52).
The thing is, Nolan(s)/Goyer don't always use one version but combine nearly every version and sprinkle them onto how the character is to be handled in their story.
