Honorable Isbulino, I agree with your House's idea about the Naples Question. Waiting seems the best option.
I must however disagree with a 'punitive expedition' as you suggest. It would require financial support; which may be given somewhere else. But if Venice, the Papacy or Sicily decide to attack the Byzantine Empire, we should then and only then strike at one of the Isles. For now we must grow, economically.
