YES!!! As all you are doing is a slight bend in the picture. then you can just use -wave. However -wave only works in the displacement in the Y direction. And in your case can add lots of extra space. To fix, rotate your picture 90 degrees (no loss of quality) run it through wave (some quality loss, to be expected) crop the unwanted space, and rotate back (or visa-versa). See Wave Distortion.. http://www.cit.gu.edu.au/~anthony/graphics/imagick6/distorts/#wave If your distortion is more complex, or perspective, then a distortion map (also discussed on same page) may be your only option using IM.
