It is currently unknown what exactly the "awakened vessels" are. The most popular theory seems to be that they are reincarnations of their sinner although the logic behind that is sketchy and inconsistent with the known awakened vessels. The issue I have with your theory is that Ma is using the body of the sinner but the sinner's body never commited the sin.

By the time Kayo comes under the Demon of Envy's influence and commits the sin, she was already inhabiting Lukana's body and Elluka (or possibly already Ma at this point) was already inhabiting Kayo's body. Therefore, your theory would then implicate that Lukana's body would be possessed instead, not Kayo's, leaving no risk to Ma's life. That's at least how I see it, unless I am missing something.
