Paladin as subclass of Fighter, analoguos to Eldritch Knight but with Clerical Spells.
Also - limitation of Domains. Every God or Goddess has 2-3 Domains and their Clerics are limited to those.
That's a cool idea, and one I've been contemplating for my next mod. The concept of this would probably need to be something like a Templar Knight, where the secret society aspect of the order is more important than the religious zealotry. They should probably have a number of custom spells too.
