After a lot of research, I think this may be a possible OT timeline (well, at least it shouldn't contradict the original scripts).
Still needs some work, though :\

"Star Wars"
This is a really neat and concise outline. I have a question about it: Did Anakin go evil, spend decades as Darth Vader, and then conceive two children with "Mrs. Vader"? That's interesting. Most interpretations of the prequel timeline that I've read about have Mrs. Skywalker discover her pregnancy while Anakin is still a good guy and a loyal Jedi. Your interpretation shakes that up a bit! It puts a very different image in my mind of who the mother was if she knew she carried the children of the Dark Lord of the Sith.
