Um -- River's life isn't reduced if you take her out of Stormcage. It isn't preserved inside of it. Stormcage is a prison, not a cryogenic suspension chamber. She's aging whether she's with the Doctor or not.

Otherwise, the parallels are interesting, though I'm not a big fan of the way the Doctor/River relationship is turning out. I'm hoping her stay in Stormcage is temporary (as in, not her whole life with occasional jaunts outside with the Doctor) until the deal with the Silence is cleared up, and then they can go have adventures. Otherwise it just looks like she's the typical mum-stays-in-the-home while Dad works in the dangerous yet glamorous Outside scenario.
