Since Lillibeth is a reasonably lofty fighter, you could give her a semblence to increase her mobility. One could be that she can manipulate her own center of mass to be able to balance on harder items for much longer times.

Narcissa could have a weapon that will amplify force she exerts when fighting. Giving her a chopping weapon or slashing weapon that can swing harder dispite her being not able to do so can make it more threatening than it would look. A super hard blade with a refined point could also be a good idea.
