Paul, 40, was on a break from filming when he was so tragically killed in a car crash. And in a poignant tribute to the star, Cody Walker, who has worked as a movie stuntman, looks set to take his place in the latest installment.
"Producers had a string of meetings right after Paul's death," a source close to production told the Mail. "They soon realized they needed someone who looked like Paul to finish the movie, and that's when they approached his early identical brother Cody."
Cody, who lives in Oregon, has been staying in LA with his mum Cheryl as the family comes to terms with Paul's death.
The source added, "They can shoot Cody from behind and at a distance, and if it's a shot they need Paul's face in close up, they can CGI it later on.
"If Cody agrees it's because he wants to honour his brother's memory. There are many details that still need to be worked out, but right now the family and cast and crew are still grieving."

Universal Pictures, the studio behind Fast & Furious 7, have made it clear that they will work alongside the Walker family and take their guidance on a fitting exit for Paul's character Brian O'Connor.
A spokesperson told the Mail, "Right now, all of us at Universal are dedicated to providing support to Paul's immediate family and our extended Fast & Furious family of cast, crew and filmmakers.
"At this time we feel it is our responsibility to shut down production on fast & Furious 7 for a period of time so we can assess all options available to move froward with the franchise.
"We are committed to keeping Fast & Furious fans informed, and we will provide further information to them when we have it. Until then, we know they join us in mourning the passing of our dear friend Paul Walker."
