Why not use Capture NX2 so you can use all those camera settings easily, but not get locked into the limitations of jpgs? Combine CNX with Photo Mechanic and you have an excellent file management/post-processing combination.
The only situation I shoot JPGs are: I need files instantly to share; or I am only planning on using the images for a quick web posting.
View NX2 will give you some NEF editing capability, but it is very limited compared to CNX.
Seems to me you are overlooking the obvious solution.
