I doubt ND could do it alone (not while the majority of it is working on UC4), but if they outsourced the hell of out it, a la MCC, it could definitely be finished in time for the holidays.
Would be interesting to see how well done the remaster of each title would be though. The MCC suffered from more performance instability than you'd have expected (primarily in H1A, Halo 4, and especially with split screen), which i expect was the result of the outsourced studios and i343 working on a very strict deadline. With Uncharted there would be 1 less game to deal with, but each would be more of a pain to port (bless ye Cell, slayer of programming hopes).
