1.5 to 2 years ago I homebrewed a (brief) campaign where I listed various Cimmerian clans (both imaginary and in RoK) with small bonuses/weaknesses etc. to each. That might be too granular for most Conan d20 players but I liked the concept. It was simply an extension of the idea that different races get bonuses/competencies/proficiencies.
E.g. a given clan "A" is good at using axes, so they get a +1 to attack and Dam with axes, but are terrible swimmers to they get a -1 to any Swim checks. Stuff like that....
Snowhawk Clan folks (e.g. Conan's pop) were known for blacksmithing (back me up here!) so they get perhaps a +2 to Craft (blacksmithing) checks. Etc., Etc.
YMMV.
