Would Star Wars have ended better with a Darth Vader Clone?

Just popped in my head after reading the story about the child actor who played Anakin Skywalker being in prison. "Damn, if he had his shite together, he may have been able to have a role in the new series"

So we had the whole clone wars, and Darth didn't know he had children until many years after.

Theoretically, he could have had a clone made, who was much younger than Luke. But when Darth & the Emperor die that secret is gone. No one knows of Anakin's clone.

This is who could have been behind Snoke, on the Sith planet, or whatever to full fill the Skywalker prophecy.
