I've done the combo stem adaptor and threadless stem. Compared to your current stem, from a weight stand point you're probably better off with your current stem. Therefore all of your weight savings needs to be in the bars. If it were me, I'd ditch those non-aero levers and work on some light weigh aero levers with the new bars. It sure will look cleaner with that conversion.
