I have tried doalign values 1, 0 and -2, but none of them seems to give "correct" results - it looks like the grey scale shape is shifted nicely and following the shape of the other feature.

I would have to see the IMHEADER outputs for the two images to be
certain of my advice.  The task HGEOM or OHGEO allows one to regrid
one image onto the coordinates of another.  This is probably what you
will need.
