BUt wouldn't you think that her boots and skin would have rotted away after being in a pond for two years? That's reason enough for it not to be her.
Nar. I do specifically recall it being made as a seperate post entirely.

And to back up your theory on the rotting, the mere fact that she's in the Lifestream at the end of the game tells us that she has in fact 'returned to the planet' and thus no longer has a material form.
