I wonder how, exactly, Urahara's method of retrieving Bankai is going to work. The way I see it, it can function one of two ways:

1. His technique replicates the stolen Bankai, possibly temporarily.

2. His technique requires the Captains to possess the Medallion that houses their Bankai, necessitating they defeat/kill the Quincies in possession of them.
