What about your current position on the bike feels uncomfortable around town? Does it feel too aggressive, like you're hunched down and you'd prefer to be more upright? Or do you feel too stretched out, like you're reaching too far to get to the place you prefer holding your current bars? Since your stem is currently set as high as it can go, if you want a more upright position you should get a new stem with a greater angle so it'll raise the bars even higher. You could also try getting it 10 or 20mm shorter to decrease the reach, too. That sounds like a good place to start, rather than trying new bars -- I still use cut-off drops as bullhorns on my street fixie and love em, nothing wrong with that.
