Here's a wild theory;
When people suggest that she's the Doctor's Wife, they're usually implying that he is yet to marry her but from her perspective they've been married a while. Well what if she's the Doctor's Wife as in the Time Lady he was married to (presumably) during/before the time war? He often makes reference to his dead children, and those children had to have a mother. Rather than being the wife he hasn't met yet, why not the woman he's been married to for however long but with a new face? There are dozens of convincing sci-fi-timey-wimey spiels that the Moff could produce to cover the fact that he couldn't tell she was a timelord, so why not?
Probably lots of holes in that, but it's the closest i'm going to come to making a serious theory.
Of course she could end up being a SUPER-RANI. Like the original, only SUPER.
