The undelying theme connecting Urahara's Shikai & Bankai abilities surely is one of the tougher ones to understand, as the Bankai ability alone is already very vague and conceptual. Remembering the time he used that modified Byakurai spell[] on Aizen, my idea was that the Shikai's concept could be something like 'remodeling Kido', or even 'remodeling reiatsu': With all of Benihime's attacks being essentially Kido-like, his Zan would just give him the ability to always easily create the right Kido for any situation (or remodel an existing one), given he analyzed the opponent's reiatsu enough etc. Another possibly theme is the idea of using reiatsu for either 'severing or (re-)binding', as the Shikai does basically this, and the Bankai takes it to another level with restructuring things on a surgical level.
