Use the reconcile3d node to get the continuos tracks and feed them into a tracker. Stabilise one plate then match to other plate. Often works.
I made 2 gizmos on nukepedia that wrap this process up. (Tracker3d to 2d and to corner-pin.) Frank has a camera stabilise method which is very good, but the above done right will concatenate transforms so try either.
