Cersei would be seriously unhappy at losing control over King Tommen.
Perhaps Uncle Kev could step in here? He did offer and he might be better at treating Tommen as king instead of using him as a means to be king(well, queen in Cersei's case)
I can't help but feel sorry for Tommen, because since Cersei is his mother and he is king, some difficult decisions may arise..
