If one includes the WW1-era Z-class and the Fret-class large torpedoboats for the lower tiers of a dutch DD-tree and fill in the upper tiers with the british destroyers that was transfered to the dutch (3 different classes, which will propably be found in a british DD-tree eventually too, so less work) during and after the war it might actually be possible to make a complete dutch DD-tree without resorting to any fictional designs.
