I was planning on creating a vizard that had resurreccion, like Tousen's. The explanation for having resurreccion is the fact that his inner hollow's unique ability is consuming any race, which allows him to consume others for increased power and the resurreccion unlocks that increased power.
The vizard is a former captain, but he lost connection to his zanpakuto spirit by getting so close to his inner hollow, so he only has shikai, masked form, and resurreccion.
I'm a long way from getting the application finished, so I just wanted to know that this was ok before I wrote it up. The resurreccion doesn't bring any additional techniques, just adds power to the abilities that already exist.
