I like the idea of the submod, though a "baillif" unit is irrelevant, as these guys weren't more than 5 or 6 for a province like the French Royal Desmene.
They were great officers, their servants(sergeants/servientes) were both professional warriors, "Village cocks", cadets from low nobility.
The image of a whole unit of heavy warriors wearring all the healme is wrong, medieval illuminations show often both knights and sergeants fighting together.
Same in Italia(where were made the healmes), the servientes didn't have healmes, and many knights wore also the chapel, with the hooded mail.

No offence, just I wanted helped you Praetorian, and good luck for the next.
