Do you consider removing Portugal in early and add them in Late game only? Since they aren't doing anything and alway get annexed or become 1 settlement vassal and add Hammadid or Zirid to balance the Mediterranean since Tunis always being annexed by Italian faction because another 2 Muslim faction near it too busy.
Also, I see that Sicily faction still appears in Late game (but not exist), maybe you can make them start at vassal of the Holy Roman Empire.
