If it is possible to limit traits to a certain legth of time ... then I would suggest the following for Athenians (and only them):

Ostracized
City: Athens
Ethnicity: Athenian
Trigger: High influence, good speaker (optional)
Effect: severe influence penalty, severe penalties while in Athens (if possible)
Lenght: 10 years (if possible)

Description:
The Ekklesia decided to prepare Ostrakos, and this man's name appeared 3,001 times or more. It was by this decision, and for his great influence on his fellow Athenians that this man was honorably banished for ten years, to rethink the effects his leadership is having on his home city.

Arhon Basileus
City: Athens
Ethnicity: Athenian
Trigger: High influence, wealth
Effect: increased influence
Length: 1 year

Description:
Chosen as the Arhon Basileus, this man is in charge of all religious rites in the city of Athens. Holding such a position gives this man a great deal of influence in the city.

Arhon Eponymos - increased managment
City: Athens
Ethnicity: Athenian
Trigger: High influence, wealth
Effect: increased management, increased law
Length: 1 year

Description:
The chief judge and administrator of the city of Athens.

Polemarch - increased command
City: Athens
Ethnicity: Athenian
Trigger: High influence, wealth
Effect: increased command, lowered troop costs
Length: 1 year

Description:
Each year, Athens get a Polemarch, a military commander and leader of the armies of Athens.The origins of this service have begun in the time of the four tribes of Attika, and continue still. You command the 10 Strategos, the 10 (taksijarh - I do not know the translation, infantry commanders), the 2 (hiparh - again, I do not know the original term, commanders of cavalry) and the 10 (filarh - do not know the original term, cavalry commanders of the fila).

Member of the Areopagus
City: Athens
Ethnicity: Athenian
Trigger: held one of the three offices (Arhon Eponymos, Arhon Basileos, Polemarch)
Effect: increased influence, law bonus, happines bonus ?
Length: permanent

Description:
Having served a term as Arhon, this man now has the right to join the respected Areopagus on the hill of Ares. There he joins all the others who have held one of the three offices in their lives. Even though the Heliaia has been given much of the authority that once belonged to the Areopagus, it is still a place where experienced leaders and rulers can be found, and to be a member of such a group bring many benefits in itself, even if that group holds little power in these dark days.

Of course, all of these are possible only if you can put in a time limit on traits. Also, please note that some names may not be correct, I am using a book on my native language, where foreign words are subject to grammar changes of my own native tongue, so they may be slightly incorrect.
