Going by the mission brief I would start TPM with the end of ESB.

Have a recap of Luke asking, "Why didn't you tell me?" and maybe have Luke arrive on Dagobah Yoda die and have an altered more ghostly intro from ghost Ben.

"Anakin was a good friend".

It could even break with tradition by being a pre-crawl prologue.

Then start the story from Anakin's entrance into the story as a child and rejig the opening scenes so they slot into points near the end.

At the end of the film old Ben could tell Luke he was wrong to train him.

The last scene of ROTS could be Ben telling Luke he must face Darth Vader again because Anakin is gone for good.

This would set the scene for a pacier less silly ROTJ.

That way it we would be reminded that it's all about Luke trying to save his father.
