Anakin Starkiller was the original protaganist, with Luke being an wise old general. Both were always male.
From the Starlog article, and I could be wrong, the character whose traits would eventually be distillied into Luke and Leia was an Imperial pilot. I only glanced at this article about the time the marketing furor of the original trilogy was just starting to die out, between circa 1985-87. As I said, I might be wrong.
Another of the original ideas for Vader had him being swathed in black silk.
Bit of trivia, who was the voice of Emperor Palpatine in THE EMPIRE STRIKES BACK?
