The closest you get (to Norah Jones) is the 'White Grand' from SampleTekk, although, and this is crucial, with the 'White' you need to set your keyboard's vel. response to "hard". The White Grand's forté notes are too strong for the chill out sound of Norah Jones. You don't wanna use them. But they are easily avoided if you can change the vel. resp. curve of your controller. I think Worra also provides patches without the hardest velocities (no ff-fff samples).
The 'Black Grand' is another option. Although the decay (right after the attack) is faster and it's mellower in its mid frequencies.
