Just buy a quill adaptor, mount the stem on it and call it a day.
Reality = Hardly anyone but you cares what your bike looks like.
I just did this to my bike, but the stem is too long. I have a shorter quill that I think I'll use and just "let it be what it is" instead of buying more stuff. But yes, it sort of looks different and more modern and you don't have to rewrap the handlebars everytime you want to change stems, but then again, once you have the right fit, you don't need to change anything else.
