There is your challenge, have the city states of Phoenicia survive and form a nation/empire that last till current day.
This does not include Carthage ruling over the Phoenicians, yes they may be included.
But have them somehow survive the Persian expansion and instead of Tyre being crushed by Alexander the great, possibly join with him and further their own goals.
Is this possible as only recently have I started re-reading stuff about the Phoenicians and Carthage
