Malcador had 12 people, 8 Space Marines and 4 humans. Before the final battle (but whilst the Seige was going on) Malcador brought them before the Emperor, who gave the green light. They then left and headed for Titan, whilst the Humans went to another moon and formed the Inquisition. Titan disapeared, and reapeared during the Second Founding, with the full 1000 Grey Knights. So no.
