Liara's natural long life would keep her around a little while (relative to the time it would take) but EDI would be the only one that would have any chance to last that long. Her life span's limitations are speculative at best though.

I do like you're idea of the bittersweet "fail" ending, but to be honest, that would have been nice to see for the control option even as a victory. That sounds a little odd I know, but it is said that the Reapers would eventually return and this would have been an interesting thing to see.
