Travis,

No, no such utility exists as far as I know.

However, it would be relatively easy to write a python (or perl, ...)
script to pull the required parameters out of the .aux.xml and reformat
them as a world file.  The actual numeric values for the origin would
also need to be offset by half a pixel.

Best regards,
