While people have said that this boils down to personal preference, it also seems to not factor in any characters from Oz the Reflection so Marrybell and/or any other female members of the Glinda Knights aren't a possibility. If Oz characters were a factor, I would say that Marrybell would be a fourth optimal choice for Lelouch since she accepted his taking over without having to be Geassed and was put in charge of the Damocles during the last stages of the Zero Requiem.
