One of the Mediator's sub-concepts is Diplomat, which may be suitable for your diplomatic courier, otherwise Agent probably works too. On the other hand, just look at the skills available for the sub-concepts and see what fits the idea you have for your character. Perhaps you want one of the Agent's skills, but the Mediator's talents and equipment? Just port it over and call it "Diplomatic courier".
As for the lawspeaker, yeah, I think Mediator will work nicely if you want a character strong in manipulation and knowledgeable about the Horizon.
