I'm not aware of any tenet of ID that says there can only be ONE designer, although that seems to be the presumption. Thus if several or a million designers were operating throughout history, radically different designs would be possible or even likely. Therefore the absence of common design in no way disproves ID. The presence of features usually accepted as supporting common descent is pretty weak evidence FOR ID. And, as noted, absence of common design doesn't count against ID, unless you argue there can only be one designer, and that comes perilously close to giving the Designer a name...
