Indeed, the whole "Is this Kodos?" thing is but a McGuffin for the episode. The question of identity requires no answer, and indeed appears to have one from the get-go anyway. The character of Kodos is not particularly interesting or relevant, either; what actually happened to him or because of him is something Kirk (!) is ready to dismiss as Not His Business in a face-to-face discussion. It's all about Lenore, and Lenore alone (or in company with Kirk, as it happens).
As said, the backstory here is a brainless mess as told. It could be retold with added detail so that it would make more sense, but this would not alter the original adventure one iota. Nor would it make the obscure incident any more relevant in the galactic scale. And we're already seen the tale of Kodos and the tales of three survivors - what could be added to that? The tale of a non-survivor would supposedly be the very definition of a non-starter.
