Well, they did have more spartans that survived in the last book, so logically they could easily add a few more.
I don't remember how many (been a while) but I think Linda, Fred, Kelly (was taken by Dr. Halsey so idk what happened there) survived.
If they had co-op they might just need a different opening and closing, and cutscenes to explain it.
It is impossible however to add too many people for co-op because they would need to make entire new missions for that.
One solution would be a huge "conquest" mode, which i'll add as a suggestion.
Have a huge battlefield with multiple bases and a storyline to it (somewhat). And maybe have marines and ODST's fight the covenant army, and you could have full teams of spartans vs full teams of elites. Although they would have to be the prophets gaurds or something to have a chance in the story against spartans. I would also suggest pelicans and dropships(old and new) taking scripted routes in the battles, and maybe having a man-able gun turret or turrets that could defend them from the banshees or other aerial fighters in the sky.
4 player co-op may work, but it would be hard to make it challenging for so many without dedicated co-op missions, which would make the game take forever (unless the used the above suggestions).
