The only way to make a third season to answer certain question while not completely ruining the story is to maybe have a stage where there is an enemy character much like Lelouche's older brother. Brilliant and heartless with a formidable military force. Since there are a small few who know of the zero requiem, they propose the resurection of Lelouche (for his ability as a tactition or whatever) who is trapped in C's world. Possibly the price she mentioned in R2 towards the end. For that to work, the knowledge of Suzaku being the new zero would have to be known at some point. That would raise questions within their ranks.

Lelouche's mother made the claim that she can return to her body so perhapse that can be used to drag Lelouche into the real world since we don't know what became of his body. A senario like that wouldn't be too extreme and can set the stage to answer questions and provide an ending that is a bit more complete.
