Is it possible to make mouth wider with braces/palate expander? (no injections, fillers, surgery, etc. just orthodontics)(photo)

By that I don't mean getting fuller lips, just like in the drawing below, mouth broader, higher (because it sits so low on my face, making my midface look really long), corners of the mouth not downturned (like they are now, making me look sad/angry all the time). If yes, how to do it, exactly? Is widening dental arches with an expander a way to do that or maybe it doesn't work that way? What are other ways if there are any at all? I have a slight overbite.
