FlightPathOBN:
In a modern aircraft with path vector symbology it seems to me that the charted (and presumably database) descent angle can be used to arrive at a DA of 1,500 at the VOR. Lacking required visual references the missed approach is executed at the VOR using the DA concept. But, if the runway is in sight (or at least the approach end) adjust the path vector to achieve a shallower descent gradient from DA to the runway.
This seems perfectly safe and acceptable especially since it is a charted "fly visual to airport" segment from the VOR to the runway.
