I'd use an emission-only gradient pigment for depth maps.

For normal maps, you could use either the slope or aoi pattern as the
basis for one emission-only pigment per colour channel / axis, and mix
them via an average pattern. Alternatively, you could try using a plain
white pigment, and one parallel shadowless light source per colour
channel / axis.
