As it's highly likely we will never have an answer as their characters were hardly a cornerstone of the storyline, I figure it would be interesting to see what the popular vote is as to which name people have personally assigned to which design for whatever reason. I probably already know what the outcome will be, but what's the harm.
At least fan-assigning the confirmed names is smidge less baseless than Giyan and Hiyan ;D
