Hey Samsung, since you seem to love the focal length (16-50S, 16-50pz, 18-55, 20-50) How about a 16-70/80 f4 that would be the FF equivalent focal length of the 24-105. A general purpose lens with a better range than standard "kit" lenses, and faster at the long end You could make it a powerzoom to keep it smaller (if needed) and would probably be a very nice portrait lens at f4 from 50-70/80. Sony made an 18-105 f4 that is a powerzoom, as well as internally focusing and zooming, but it is still a bit large and bulky. Decreasing that focal length should help decrease size. Yes 105mm is pretty awesome for range but 80 would be enough for general purpose use while still keeping size down.
