You've said previously that the molecular structure of metals serve to act sort of like the Aons in AonDor. Why, then, can mists power Allomancy? Shouldn't the metals themselves be the things causing the powers? And if metals don't cause the effect, how can a non-Feruchemist burn a metalmind that has been 'unlocked' through identity tricks and get a boost of an attribute without Feruchemist sDNA?

I was trying to figure out how to answer this, and then I realized while driving to get a hair cut that you were regarding this wrong in a fundamental way. Remember, the source of power for Allomancy is EXTERNAL while the source for Feruchemy is INTERNAL. This is a fundamental difference discussed in the series.
When you burn metals, you're drawing power from another place. When you tap a metalmind, you are drawing power that the person has created--a battery developed by themselves, so to speak.
So I think that's going to answer the source of your confusion.
