Yes, that is certainly possible (it is what we are doing now). But this step is already one where the current osmarender recursion errors occur. So we wouldn't get rid of these errors here.

You can hand the complete SVG to inkscape telling it to render only a z13 area, however it seems that inkscape still loads, processes the whole file, so that oesn't save any CPU cycles or RAM. You would have to have an SVG preprocessor that splits the z12 area into seperate z13 tiles, keeping city names and surrounding area's intact. I don't know of any tool which could do the job, and I get the feeling it would be a rather complex job to create it. But if somebody feels capable of implementing something like this, I will happily use it.
