With how standard biosculpting and such have become, it's not really out of the box for any metahuman to differ from the normal states of their race. Skin alterations, bulk thinning, eye tinting, tusk removal/cutting, etc. are all things that people do to fit in. If shorties in the real world go through procedures that break their bones, force them apart, and force them to regrow just a slight bit longer than original, I don't see male gnomes commonly getting those cool goatees or stashes to fit in and not look like kids being out of the question.
