In a way, the theory does make sense. If you look at all the sinners (excluding the Clockworker's Doll for the moment), both Cherubim and Kayo did not have their birth appearances while possessed by their demons; even if a change was the result of the Demon's power. Cherubim asked for his brother's face when he made his contract with the Demon of Lust.

However, I'm throwing in the idea as to why the Vessel of Lust hasn't awoken yet might have something to do with Cherubim getting killed by the golden knife, the Wrath vessel. I can't say the same for Kayo because her life, and death, after the murders is only described as "she continued on with her tailoring work".

Now someone might say, "Well Gallerian was killed by Wrath". Yes, he was killed by the person POSSESSED by Wrath; not the Vessel.
