First off, Gigai are only for the Human World, not Soul Society, because they're basically shells for souls to inhabit, such that they become visible to non-spiritually aware Humans. It's basically useless in Soul Society. Well, Urahara did create special gigai to stabilise the disintegrating souls in soul society during Turn Back the Pendulum, which might be where BoschePG is coming from on this. Given his expertise with gigai, who knows what he might be able to do with them, but that is not something that we can say he has ever been hinted at be capable of.

But further to what Xilinoc and GodUrahara wrote, in order for this to happen, Sajin would need to go to Urahara or vice versa. It is questionable whether or not urahara knows of his situation as all that was said was that he was going to be acting on his own. Kisuke is a bit preoccupied with the attempt to enter the royal palace at the moment anyway.

I don't see this happening before the series is wrapped up if it happens at all. I don't rule it out entirely given how Kubo has not left certain sacrifices/etc stick (deaths, maiming, etc).
