Is there any particular reason you're using that projection?

If you just want an azimuthal projection, Stereographic is a lot easier to draw as a graticule in it is made entirely of circular arcs.

Also, if you're going for a 'two hemispheres' type map, Stereographic is the projection normally used while Gott-Mugnolo Azimuthal is a bit anachronistic. It's also typical to line up the graticule with the hemispheres in such maps.
