Well there is a sacrificial knife mod that lets you convert living troops to undead, translated Knights, horsemen, veterans, gunners, demons, [ogrov] sacrificed will become black knights. The interface for the knife mod is in russian but its application is simple enough you talk to the knife and select one of your armies, if you selected a valid army to convert you will be taken to a second screen where you choose the second option, if you then use the knife troops will be converted.
