Bleach: Hollow Flash

Awhile back, someone mentioned Aaroniero being able to use one of their absorbed shikai in base, and you said it was an interesting idea and deserved its own post. It'd be neat if, after successfully absorbing all the shikai you can, you would gain the ability to use a shikai outside of your Ress. You would gain no boosts from doing so, as you are not using your Ress, and the Zanpakuto Spirit of the original shikai would lend you no power.
