Urahara can be... I am a bit doubtful there. He has proven to be threatening, by discovering that Hollows act as a poison to Quincy and inventing a way to bring the Bankai back to the Shinigami. Yet.. He cannot bring back one of the stronger bankai, Zanka no Tachi, due to its user being completely erased, and the act itself only served to enable the Stern Ritter to utilize their Vollständig.. So they seemed prepared for his doings. Not that the Shinigami didn't manage to turn the table in their favor either way.
