Oh, good idea!
Ritual Caster would fit in well for a non-Cleric "shaman"-style Barbarian, especially since we house-ruled Ritual Caster can learn rituals from any class (you don't have to pick just one). I would probably start with it and pick up PAM at level 4 since the other two PCs are good fighting types already.
I'm loving the Ritual Casting Loxodon Barbarian! I'm thinking you might should do a 2 handed weapon instead of spear and shield? Your con + rage should cover your survivability IMO. I'm not even sure about PAM at that point as your str bonus on heavy weapons would add +2/+1 going from 16 to 18 using your houserules. From an optimization point of view that's impressive!
