Something to consider: In reducing intersections while keeping nodes as close to their original positions as possible, what is the importance of each requirement? In your example, you could reduce intersections, but that would require moving some nodes a significant distance.

If the minimizing of intersections is not an absolute priority (and given that zero will not be an option if the graph is non-planar), then is it really that bad to have a few intersections if they improve the match to original position?

To me, at least, the example graph looks like it could be a reasonable tradeoff.
