The model for the NPC with the elegant mask is a generic NPC model that can be found in many H2 and H3 maps. IO reused a lot of their voice actors for the past 3 sins (With the Pride VA being the “Who’s throwing stuff around here, come on” guy, the Sloth VA being the same voice as Terrence Chesterfield, and the Lust VA most likely being the same person who voiced the Washingtons)
Don’t know if IO would be willing to make a completely new NPC model for a single escalation.
