What is missing from your message is whether this data is 2D or 3D. Assuming they are 3D and the coordinate system of models has not been modified/altered between the two landmarking sessions, you can just append the sets together, just make sure to remove those four redundant points from one of the sets.
If it is 2D things get more complicated depending on whether you have taken the landmarks from the same view or different views.
