If i`m not wrong, to do it you will need to apply a filter in your code, to change the twentythirteen_custom_header_setup, so when you load your page the function will register the older function before your new child theme function , and so you will need to filter that an call again to overwrite it !!

I was looking the xml file generated by wordpress i was having the same problem and i just look at “filetoimport.xml”… and just replace some
paths in lines using copy and replace, look, my last wordpress was installed in https://localhost/wordpress/ but my new wordpress was installed inside localhost/tosin/ and old media or jpg was in localhost/wordpress/wp-content/uploads/assets
i just simple create that folder inside my new installation … localhost/tosin/wp-content/uploads/assets/, and after that i change all lines in my .xml file who have that path localhost/wordpres/ to localhost/tosin.. and that’s works pretty for me
