The quality of the taking lens is not the only factor that will determine the sharpness of your final print. Other obvious factors will be the quality of the tripod, the head on which the camera is placed, the stability of the camera and the groundglass alignment. Then there is the printing side of it, either using a scanner or wet darkroom. You realy have to address the whole system to reach optimal sharpness. Looking at the tables you've given in your question I would not invest in another lens, also because i think there is more to a perfect picture then sharpness.
