Can you cut down the height of a quill stem?

Which sort of wedge does it have Ed?

If it is sloping, pretty easy, cut off at exactly the same angle, at the required length.

If it is internal it is a bit trickier, as you need to cut it off, then saw slots back in, but also very do able.

I was about to post that it was only doable with a sloping wedge. Obviously some people has the skills.

If you have an internal quil stem that you like,
would it not be possible to find a cheapy sloping stem,
scavange the wedge,
cut the existing stem to the same angle as the cheapy stem,
and install the sloping wedge.

Just a thought.

(BTW. I personally like to use a hacksaw, cutting a little too little off, followed by use of a fine file to finish)
