I don't know if there is any real way to escape from x:y:z ratios of 1 : 1 : 1/(1852*60), as anything other than that is numerically synthetic. if taking up the 1:cos(lat) aspect ratio adjustment perhaps rather than converting the elevation data to degrees, we could convert the ew, ns to "meters" to get ratios of 1852*60*cos(lat): 1852*60 : 1 as the cheap and dirty projection. for global lat/lon views you probably wouldn't want to do that though.
