Yes, most definitely doable without too much hassle.. with a standard set of needle files. But again, you don't want to take too much off and want to go super slow on the filing.. as you merely want a fraction off.
I've circled the (inner) area of the lug which had to be filed (Google pic).. as I don't want to run any other risks by removing it again to take pictures, but you can see it's fitted to my modern Speedy (yes, the lugs are quite scratched from previous bracelet fittings).
Minor correction to my previous post. The correct end link reference is 812. Not 821.. I'm probably somewhat dyslexic..
