I think Vader was always intended to be Luke's father though, even in the pre-ESB universe. His name even implies it.

*sigh*

Actually, Lucas' earliest surviving notes on Vader's name don't say anything about the word "father"--rather they suggest the name was a combination of the phrases Dark Invader and Death Water.

Also, I highly suggest you read through the Leigh Brackett script of ESB.

And even if Vader was always intended to be Luke's father, a universe in which he's not would be interesting. As far as we knew in 1977, mrs. and mr. Vader named their son Darth and Darth betrayed and murdered Luke's father.
