Greeklang in Sicily? (Re: Collabgreeklang in cbb)

[Zythros Jubi]

I planned to make a Hellenic conlang spoken in coastal Sicily and Naples (specifically, Amalfi coast) but abandoned later. I just wanted to add some flavor of Sicilian (and Neapolitan) into a descendant of Koine with heavy Doric influence. I used Tsakonian as reference, and drop original final consonants, then I was hesitating how much noun cases to retain. Tsakonian seems to show cases by inflecting articles like German does. Then when I checked out Sicilian grammar, i found that there are just 3 unstressed vowels: a, i, u. This can dramatically add to homophony, and shift in stress (common in Greek) can be a tough problem.

Are you familiar with Griko?

Unfortunately not; but I've read grammar of Calabrian Greek. Some dialects even add an epenthetic vowel after -s.
