I like that idea. I'm not very experienced with character interactions. Potential issues I see areYou could block it in the concubine interactions. If you look atcommon\character_interactions\00_marriage_interactions.txt
there's a common check in the three concubine interactions make_concubine_interaction, find_concubine, and offer_concubine, ofallowed_concubines = yes
, and likewise incommon\important_actions\00_marriage_actions.txt
the action_can_take_concubine and action_can_take_consort the sameallowed_concubines = yes
.
I don't think the allowed_concubine trigger is moddable, but where ever it appears in those five locations you could add in your own code that if the character is a member of your modded faith, they must be the head of faith to allow the concubine interaction to be valid.
1. Would this create a separate 'take as concubine' option on the interface or change the current one.
2. If it did change the current in-game option, wouldn't this then apply to all faiths?
