I think that would be a good idea - essentially a mapcomposer on steroids. What would be needed (just some ideas) is: a) the possibility to send a map with selected layers and everything to inkscape as an object this could be done via gdal, but I *think* it might be easier to make this directly b) implement the basic map related features (north arrow, scale, legend, ...) in the same way c) make sure that inkscape (for the map related elements) is *aware* of the fact that it is a map, i.e. if the map is rotated, the north arrow should rotate as well, scale changes, ...) I don't think the pdf driver from gdal offers the flexibility needed (but I must admit I don't know it).
