He's using it to keep himself alive, reimuing his soul with investiture

If it where that easy he would have said yes.
....
The metal is a key, it has no power of it's own, how many times do we have to say it. And Genetics doesn't change anything about it.
It's also possible for Fullborn to survive for extended periods of time in a better way than Atium Ccompounding, doesn't mean that looking at it a different way is what it is. The answer to how they use it is form a connection to Honor.
no, they use it to acces Harmonies investiture, not theirs.
no it isn't.
no
False on every level, (Excluding bonding normally)
Then why can't the Fused use it?
Or Vasher awaken with it?
You are so wrong it's not even funny, that simply isn't the case. That's like saying anyone can use stormlight to fuel awakening if they think about it the right way.

well, weak nuclear force yes, but for the most part.
they don't need quantum theory, all they need is someone to say

so, what id we made anitiron or what not,
1 soulcast later, and they have the power to destroy cities
