I don't know whether Inkscape chokes on the actual z12 rendering or rather on the rendering of a complete z12 tile at zoom 17 (which contains lot's more stuff). If its the latter case we could theoretically render the z12 in one go and split the svg file in smaller pieces and feed them to inkscape for higher zoom levels. It might not even be much code to do that, however, I don't think I'd volunteer for such a task.
