Cerberus Russia Faction - Yes or No?

Been thinking that we need more baddies for all our OCs to fight. Should we leave Cerberus dead after ME3 or can you see other countries having their own branches still running? Maybe they're good versions that aren't as willing to sacrifice people, even for the great good or maybe they're way way worse? 

If you guys think it's a good idea I'll complete this model of Arnie as their leader. The pic above is just a quick slap together to try and get all our brains thinking of possibilities.
