Make him take some space - he is important and would have guards and such with him. Also, you could really make him a troop type and occasionally lead assaults and defend the planet (s)he is on.

You could also add a component (in the name of roleplaying) called "Leader's Quarters" and make it a smaller cargo component all around. Could also give the ship a bonus against boarders since they are defending their leader.
