What would happen if an Awakener tried to use Breath on a Dead-Eye Shardblade?

I am not sure if this has been asked before... It just popped into my mind and made me curious.

Would the awakening command have a effect on the dead-eyes? Or would nothing happen?

I doubt it would have much of an effect, because deadeye Blades are essentially solid Investiture, right? I imagine that it would be similar to trying to Push/Pull on a filled Feruchemical metalmind. It's really hard to do, but maybe with enough effort something cool would happen. I might be completely wrong, but it seems to me like Breaths wouldn't have much of an effect.

It's an interesting question.  As Stormblessed says, it would be hard to muster enough breaths together to even have nay effect due to how invested a shardblade is, but The Godking probably has enough. so If Susebron, in a fit of impiety, decided to burn through his hoard of breaths in order to awaken a shardblade, what would happen? I honestly don't know.

for one thing Shardblades are, or at least were, sapient beings, and based on what we have seen of them in Shadesmar, they are almost certainly not dead, precisely.  I don't think we have seen a case, other than granting breath to another person, of someone trying to awaken another already living thing.  It's not clear that such a thing is even possible. but it also isn't 100% clear that such a restriction would apply to a spren/shardblade - they aren't exactly living things in the biological sense, at least not in the physical realm.
