Trung Sisters, or just Trung Trac, the more "important" one, could be a Vietnamese female leader. Indonesia/Majapahit also has Tribuhawana (however you spell that). Both would be qualified choices for their respective civs, though the Trung sisters more so because they're seen as one of the most important national heroes of Vietnam (if not the most important, given that they led the first major fight against the evil Chinese - which is a reoccuring theme in Vietnam's narrative of its own history).
I could see Italy as the one with another female leader, though they already have a European female leader this round. Then again that didn't stop them from adding a bunch of female leaders from Europe in G&K.
If Italy is in, it wouldn't be unreasonable to expect Queen Margherita, Caterina Sforza, or Lucrezia Borgia.
Personally, I'd want Caterina of the three; she is amazing in Assassin's Creed II
