Basically the XYZ mosaic mode as it is implemented currently in Hugin
requires that the mosaic photos must be mapped to a plane perpendicular
to the view direction - In practice this means that what you are trying
to do only works if the panorama is rotated such that the nadir is in
the middle of the canvas and not at the bottom.

This isn't so bad, the nadir-in-the-middle image looks a bit weird, you
can just reload the stitched equirectangular result into a new single-
photo project and straighten it there.

There is code in libpano13 to do this rotation all in one go, but it
isn't enabled in Hugin - I would be concerned that it would be way to
confusing - The two step stitching is conceptually easier.

Title:
  Translated nadir image not mapping correctly

Status in Hugin - Panorama Tools GUI:
  New

Bug description:
  If an image is mapped to the nadir of a panorama and all translation
  parameters (X,Y,Z) are set to zero, the image is properly mapped and
  covers the entire nadir of the shot.

  However, if any of the X,Y,Z parameters are non-zero, then the image
  is cut in half and only occupies half of the nadir.

  This bug appears both in the preview and in the final image and is
  important because, typically, the nadir shot is handheld and non-zero
  X,Y,Z parameters can improve the fit.
