you could go with a Nashbar Trekking Bar, though you might need a different stem, and it is pretty wide.

Offers similar hand position that sweeps back much less, in addition to a few more hand positions. I have them on both my road hybrid and MTB. Love em, and wouldn't trade them for anything else.

Here are some threads displaying how people set them up. Mine's set up similar to this one, but with ergon grips on the "flat-bar" part.
