FYI Surly not too long ago introduced a drop bar with more rise called the Truck Stop Bar which might (or might not) be a solution. Here's the info:

Designed to combine what’s good about drop bars with the benefits of a riser, the Truck Stop Bar offers welcome relief to the road-weary traveler. Just like with a standard drop bar, you’ll have multiple hand positions at your disposal so you can stay comfortable and in control for the long haul down the Big Slab. And if it’s a more relaxed, upright riding position you’re after, 30mm of rise will get you there. So, if you’ve accidentally or intentionally cut your steer tube too short, here’s your chance at redemption. Also suitable for taller riders who’ve exhausted all other options for rise, it comes in three widths of 42, 45, and 48cm. Lightweight aluminum construction, CB radio not included.
