Maybe, but you can get the Soul while still saving Solaire, can't you? Doesn't that debunk the theory?

Although, I do think it's interesting that they are found in "Heaven" and "Hell", but it's hard to tell whether or not it's intentional, given that Duke's Archives = Heaven is a bit of a stretch (though I can see where you're coming from).
