I haven't done one myself, but theoretically the runout should be best matched if you swap the waist cutoffs. So glue the treble side waist cutoff to the bass side lower bout, and vice versa.
Flipping it over across the grain inverts the runout, but flipping along the grain doesn't. And to get the straight edges together, you have to do a horizontal flip (or rotate 180 degrees, which is equivalent to horizontal flip followed by vertical flip). So start with the opposite runout and you can't lose
