great - the whole point of the scripts are as examples really, not that 
you need to send patches back to show everything that you modified, but 
that you modify to use modules and code to do whatever special thing you 
want. The hope is that the modules are flexible enough that you can 
write the script to accomplish your goal.

BTW - the one thing you can't recover from the GBK version of the file 
is the source of the accession number -- you have hardcoded in 'ref' but 
it can be 'gb', 'emb', 'sp' etc this field isn't part of the genbank 
record unfortunately -- one can come up with a pattern based on 
knowledge of accession number formats but I don't know that anyone has 
really been that worried about that sort of thing to try and write 
something for it.
