I would use a combination of a flipped up stem and short reach bars. Get some modern bars that don't have a ramp-down angle to the brake hoods, with a short reach in the 75-80mm range. I like Easton EC-70 or EC-90 bars, but only the EC-90 comes in the 38cm C-C width that I prefer. There are cheaper aluminum versions, with a similar bend.
As for stem angle, if a 6 degree flipped up is not high enough, then you can go to a 17, but keep in mind that the actual length is significantly reduced when the stem is flipped up, so you probably don't want a flipped up 70mm. A 17 degree x 90mm is similar to a 75mm.
