Yea, hate to say it, but right now I don't really see a female companion my male (or female) PC might fall for either... Shar priestesses are legendarily self centered, narcissistic and more often then not outright sociopaths, and I won't even try to imagine what Githyanki woman go for.
Also, no, none of the two girls we got right now would represent the typical Fearunian heroine... not in a world where a Dove Falconhand, Catti'brie Battlehammer and Danica Maupoissant exist.

The guys are quite varied already, though... so, good work there!
