Is the following what you wanted?
myContourData = ContourPlot[ Sin[x y], {x,1, 2}, {y,1,2},
AspectRatio->Automatic];0;
Show[
(N@ Graphics@ myContourData) /.{x_?AtomQ, y_?AtomQ} -> {x, Log[y]},
AspectRatio->Automatic];0;
The key point is that you need to convert your contour data to graphic
primitives with Graphics@ myContourData.
