Interesting, looks good! I already made most my comments in the dev diaries (liked most, except I'm not a fan of the extra empires).
I like that the province of Aprutium is being split off from Spoleto. I understand the decision regarding the titular kingdoms of Naples and Trinacria, but I do like the option of creatable titular titles. Otherwise a ruler of Sicily could relatively easily get two titular royal titles, but alternatively extra conditions could be used, however that's something for the modification subforum.
