You read my mind Dom.
The first row around the bottom would provide the donor links to repair the holes, but you need a very steady hand to open the links and keep the pins. 
And a very fine heat source like a jewellers blowtorch.
A jeweller could do it for you? You wouldn't lose any significant length on the chainmail from donating the last row?
Its a lovely helmet, is the caligraphy chiselled/hand-cut or etched?
I suppose like many, I am an admirer of arabic caligraphy (Although I understand none of it)
Have you translated the panels on your helmet?
