I've been experimenting with your substitute DB19, built from 9 1/2 pairs of angled 2-pin 0.1" header. I think I have a slightly improved solution: 3 straight 5-pin 0.1" headers and 1 straight 4-pin 0.1" header. The spacing between holes on the DB19 isn't 0.1", so it's not quite the right fit, and a 9- or 10-pin header strip won't go in. But if you use 4- or 5-pin strips, the pins have enough bend to them that they'll fit snugly.
