Some of the Bleach captains could potentially ally with the angels.

This alliance could be based on mutual protection and the goal of maintaining peace in the supernatural realm.
Well, the Bleach captains' abilities are quite powerful. For example, Hitsugaya's ice-based zanpakuto could be used in interesting ways in the DxD world. It could freeze demons in their tracks.
