Can Feruchemical Savants tap metalminds in their sleep?

[JustQuestin2004 he/him]

So, I had a thought about Feruchemy's version of Savants, who are usually Compounders due to needing more power than they can naturally produce with Feruchemy alone, and specifically a small wrinkle in the idea of Atium Compounding and with Marsh.

How could an Atium Compounder live for so long, if they die from old age the moment they stop tapping when they sleep after they reach a point beyond their natural lifespan?

How does Marsh do this? Easiest answer is that with the 20+ Hemalurgic Spikes he has, one of them probably grants him Feruchemical Bronze so he never needs to sleep in the first place. But what there is another way?

Savantism warps the soul in a deep, fundamental way. Making the powers you're using become even more natural to you and allow you to do things that aren't normally possible or feasible for non-Savants.

The only thing we know about Feruchemical Savants is from Miles Hundredlives, where WOB stated the reason he lived so long when being executed by gunshots over a dozen times, is because he was a Savant.

What if another benefit granted by Feruchemical Savantism is to become so used to be constantly and consistently drawing on the power of your metalminds that you can even do so while you're asleep?

Spook was able to burn tin while asleep, and I think Miles had to constantly tap health for some reason. It seems that the body almost becomes addicted when someone becomes a Savant, and certain rules like not using magic while asleep start to break down. I'd say Miles did this while asleep, and Marsh is probably an F-Atium Savant at this point.
