Oooh, yes, that's a very interesting perspective. I mean, I still have the same issues or lack thereof in my own weird configurations, but as I said in the post, it does make total sense to me that she would take care of Cal - her behaviour to Donna, Amy and Miss Evangelista demonstrates that she is very compassionate. And I do like the idea that this isn't River's afterlife so much as Cal's, and Cal wants a bedtime story. Even though eventually that tale-teller will fly the library.
