That won't change justification, but that will relieve interword spacing a bit. I thought I'd put something like that on the wiki but apparently not, so you're welcome to share your code with the outside world :) Also, you can justify an entire paragraph with letterspacing simply by adding glues between each nodes in pre_linebreak_filter, but that's another story.
