Storing Kinetic Investiture through Nicrosil-Feruchemy

[Brightlord M. Alhstrom]

Brandon has talked about how when an Allomancer is burning metal, the metal isn't the investiture, so much as a focus or key used to access Investiture from the Spiritual Realm. So, here is my thought:

Would an Allomancer/Feruchemist be able to store the Investiture into a Nicrosil Metalmind as it was flowing through him? And if he were to tap it, would it be just like if here were burning the metal then instead of earlier? Would this make it possible to get the effects of Allomancy a lot faster? Like, tapping twice as fast, so your pewter-enhancement is twice as effective?

What about an Elantrian/Feruchemist? If he were to activate an Aon, then start tapping Nicrosil, is it possible that the Investiture that would have been used to create the effect of the Aon would be siphoned into the Metalmind? And if you were to tap this metalmind, would the investiture just sit there, or would it try to act as though you had just activated the Aon? Could you (once again) accelerate or decelerate the effects of the Aon?

The same kind of questions could be asked of Surgebinding.

 

To me, the core of the argument would have to do with Kinetic investiture, and whether the investiture ever passes through the body of the Feruchemist. It might be that you can store some of the metals' effects (like Pewter or Gold) because they affect you, and only you, and/or part of other metals' effects (like Copper or Tin), but only those effects directly tied to you (so, hiding your own Allomancy or protecting yourself from Emotional Allomancy, or heightening your sense of pain/touch, but not sight, hearing, etc.). Or you could store an Aon that would heal you, but you couldn't store an Aon that would heal someone else.

 

And finally, what about an Elantrian storing the investiture fueling his body? Could an Elantrian intentionally go into a Shaod state by siphoning the investiture that would make him Elantrian into a Metalmind? If he did so, then tapped the metalmind, would he shine brighter? Or maybe if he spent a month as a Shaod Elantrian, then he'd be able to use the metalmind to spend a month as a normal Elantrian while away from Elantris?
