I would prefer that each time you have a revolution you become a new civ.
i.e.
Celt -> Frank -> French/German
Roman -> British -> US
Lord knows the "Chinese" civilization is all about revolution and dynastic change. I think the Chinese have a better claim on Religious and Industrious. They seem to weather governmental change much better than their european counterparts. I would argue against scientific because even though they had a HUGE tech advantage in Polo's time that was countered by the fierce isolationisim and a caste system that hampered scientific experimentation for over 1000 years.
Each time you have a Revolution you could pick a successor empires to become i.e History of the World (Hasbro board game).
If you keep at least one of your old traits you keep the old name. like the US starts as an expansionist & industrius Republic then becomes a Comercial & Industrius Democracy
