So, like lengthening "arms"`, adjusting height (in a minor way, no BMR effect) and changing "hair" style? Yeah, visual and stylistic is one thing, once it become practical I'd have to consider it.
The limited shapeshifting does seem to indicate larger shifts in shape (badum tsh), i.e. humanoid to non-humanoid form ... but it doesn't, as you point out, cover small stuff. I'd consider minutes, or even seconds, in some cases. It depends. I'm just starting to think of Runcori contortionist, pick pocket and lock picker...
