Aviar powers fueling other investitures?

[Trusk'our he/him]

Aviar seem to draw a small amount of investiture directly from the spiritual realm to fuel their powers, without needing to use a catalyst, like how Allomancers need to. If someone could Hemalurgically take an aviar power, could they use this to get ‘free’ fuel for any other manifestations of investiture they might have, such as Surgebinding or Allomancy?

[Honorless he/him]

Hmm... possible. Allomancy already draws power from somewhere else though, no idea how you'd put Aviar Investiture to filter via the metals. Even less of an idea of how you'd do that with Surgebinding, where presumably your bonded spren acts as the filter... or the bond with you might supercharge your Aviar. We might get that latter answer from Lift from enough.
