Bah... l'auteur le dit sur la page du nexus:
"The Skyrim Unbound MCM special options menu has four faction choices available at any point during gameplay: Imperial, StormCloak, Bandit, or Forsworn. If you choose either of the Civil War factions, the opposing army will attack you on sight. If you choose either Bandit or Forsworn, guards and soldiers will become hostile towards you but the other members of the faction you side with will treat you as one of their own. This is fully compatible with any mod that edits factions. The MCM can and must be used whenever changes are desired or if neutrality needs to be restored."
Aprés ce que tu peux faire c'est combiner ce mod avec celui la: http://www.confrerie-des-traducteurs.fr/skyrim/mods/jouabilite/lhabit_fait_le_moine , tu devrais ainsi pouvoir passer inaperçu.
