Interesting concept! I don't know if I'd be able to write it myself, unfortunately, because I'm not really confident with writing Saionji, but I hope you're able to find someone to write it (or you could try writing it yourself; I don't know whether you're a writer, but it might be worth a shot!). Thank you for the suggestion, though. It's nice to meet you, whoever you are!
