This accident is similar to the one at Centennial where a Cirrus overshot 17R and collided with a Metroliner approaching 17L. In each case the airplane that overshot was a high performance model where there’s always the possibility of a pilot who is not too experienced yet with the much higher ground speeds and space needed for maneuvering that aircraft. Also in each case the runways were very close together, yet ATC procedures are depending on separation to be maintained by the pilot in a fast airplane in a descending turn. Bottom line, maybe it would be advisable to change those procedures.
