They would be just being born around the start of the story unfortunately. But in a different story, perhaps.
An update on the poll.
Mobius is currently dominating in first place.
All tied for second are Bronya Zaychik, Bianka "Durandal" Ataegina, Seele Vollerei, Eden, Sakura (Previous Era), Yae Sakura, Kallen Kaslana.
All tied for third are Raiden Mei, Kiana Kaslana, Fu Hua, Rita Rossweisse, Li Sushang, Natasha Cioara/Raven, Aponia, Vill-V, Rin (Previous Era), Pardofelis, Sirin, Avrora, Ana Schariac, and Herrscher of Sentience
All tied for third are Vita, Alvitr, Susannah Manatt, Eleanor Schariac, Bella (original human), Agata, Wendy, Cheng Lixue, Patricia Highsmith, Salome Jokanaan, Shub-Niggurath, Shigure Kira, and Dark Seele Vollerei
Dead last is Galina.
Aponia is being polled only because I am not sure how readers will react to the idea of Aponia and Suzaku as a couple.
I also added Cheng Lixue, Patricia Highsmith, Salome Jokanaan, Shub-Niggurath, Shigure Kira to the poll for consideration partly because I want to leave no stone unturned, but also some might question why I didn't since we got Tingyun, C.C and other potential candidates who are really quite old other readers might use as a point of argument.
Others like Bronya Zaychik, this is their last chance.
Other characters like Wendy, Alvitr, Bella, Avrora, Galina, Eleanor Schariac can probably be adapted into the harem and certain liberties can be taken with them due to their short term appearances in the story.
Lastly Ana, although I am leaning towards Owl and Ana, I am keeping Lelouch as a back up pairing in case things play out different than expected.
I think seven votes might be all I'll get, but I was hoping to generate more discussion and debate since I am also trying to figure out who would be more accepting of a harem and how they could be inserted as deciding factors.
