If they're going to send someone at all, I bet that they'd send Shihouin Kurama, and probably more or less nobody else. Because Kurama is one of the few people capable of fighting Raian as more or less an equal. Furthermore, as he is quite certainly the most powerful Captain they have, if he fails in the task they can deduce that it's not something worth pursuing. The fact is, it'd be silly to assume that the Soul Society believes the Omnitsukido even stands a chance against Raian, it'd be like when Yoruichi dispatched one hundred of them single-handedly. Who knows, maybe they might send someone like Kenshin Yagami (Spirit) instead, that'd be interesting.
