I wouldn't mill the head tube, but then again, I don't have the workshop to do something like that precisely. Can't imagine having a go at it with a file would be a good idea
I bit extreme, but you could have someone with the correct tools, knowledge
and expertise. Mill .5cm + off the head tube.
Should be plenty of extra.
