I'm going to +1 this because while I enjoy diplomats and playing as one, I always liked the MP. I believe it is a fun way to RP as long as there is a good leader of the MP. Although I will say it may not be completely necessary with diplomats, and I have seen some idiotic MP on afghan. Also I'm not sure if Garnet is very interested in adding this. But like I said I would really enjoy this, but that is my two cents!
TLDR: +1
