Niek, there are a few places in UK that will reline brake shoes, of whatever size......and its not expensive, so I have never bothered with doing it myself (also bearing in mind that my riveting skills are rubbish!). Eg Custom Brakes & Hydraulics, Sheffiled.
Over here in The Netherlands I know someone who can replace the lining, he did it for both my Matchless as the Ariel, was 40 eur for a front and rear set...
