Mod Proposal - Does this sound interesting?

Hello! So I'm looking into making a mod (not getting halfway through one class then quiting) and I wanted to gauge what you all thought of it since my idea is a little different to most other mods that I've come across.

My concept isn't to add a new class, but instead to add a new collection of roaming enemies (the kind you can find in any dungeon ala the Spiders/Cultists/Brigands) intended to be what creatures come from the holy-power-place. It would just be 2-3 Enemies, with one being a 2-space powerhouse for the boss. In terms of stats I think they would focus on Stuns and Stress, with the Player having to work through the stunners quickly lest the Party go insane. Or Perhaps Stuns and Debuffs, with a long fight resulting in Lepers with a -40% damage for the next 10 turns, crippling the party.

SO does this sound interesting? What combat focus do you prefer (Stuns + Stress or Stuns + Debuff)?
