Found a rather neat mod. http://notahugesecret.deviantart.com/ar ... -639773169
Changes one of the characters to be a rather plump country girl along with her dialogue, romantic events and various holidays. Rather enjoyable to just see a BBW walking around the little town even if you don't go for the romantic path. Some other mods that might benefit this are here.
