Did it and still doing it on Sir Walter. Niot a problem and have a couple hundred miles on it. The threads don't smash down, as the last time I changed the stem they were still very much intact. Why did I do it? It was originally a cheap-as-i-could-build-it project and I had numerous threadless stems and an extra HS in the box and the fork had enough length to the steere tube to try it. Have not found a reason to change it yet.
