In a YouTube video from 2017, the YouTuber 6SpeedFletch showed in the video what the original idea for "Furious 7" was before Paul Walker had passed away in November 2013.
The script, dated 08/09/2013, written by Chris Morgan shows how different the plans were and what was instore for the future of the franchise before that changed.
-Sean Boswell (played Lucas Black) was set the have a larger role in the story than just a brief cameo, he joins Dom, Brian and the rest of the team for Mr. Nobody's missions including the rescue of Ramsey. The script also shows him saving a rivalry with both Roman and Tej. In the end of the movie, he is fully accepted into Dom's family along with Ramsey. Interesting concept, but I think the real reason that this idea was dropped because Sean was so far removed at that point, and Dom already had his current team in place. They all worked together in Fast 5 and 6, and Dom didn't really need "just" a driver (which was all Sean was). Bringing him in kept the continuity, but there really was no need for him on the team in F7. Besides, no one but Han really knew him well.
-Hector had a bigger role in the story, he shows up during the team's final mission against Deckard Shaw.
-Brian is present with Dom when visiting Hobbs in the hospital.
-There is subplot of Letty's character, when she visits the hospital, she has a flashback to the fourth movie, where she was presumed dead, but in a coma, but the flashback features Gisele (Gal Gadot) knowing that Letty was pregnant but lost the baby due to too much blood. Probably a good thing they nixed this idea as it is too dark and depressing.
-In the climax, Dom's fight against Deckard Shaw is more brutal, Dom's first shoots Shaw in the shoulder with his shotgun, the fight is more the same, but then Dom takes a severe blow from Deckard but refuses to give up still fighting but gets hit again which would take him down to his knees, Shaw then says "Just die Toretto" which causes Dom to rise up and take out Deckard and wins. Another change in this scene, when the building collapses, Shaw falls, but Dom his caught in the rubble does not end up throwing the grenades at Jakande's helicopter. The rest of that part of the ending is the same when Brian, Hobbs, Letty and the rest of the team find him the rubble.
-Instead of the film ending at the beach, in the original script shows the team (along with Mia, Ramsey and Sean) celebrating in a diner, with Hobbs showing up with a Secretary of Defense (a role said to have been written for Helen Mirren) offering Dom a clean record for stopping Deckard Shaw and recovering the God's Eye. He gives the Secretary the God's Eye, but throws the clean record away after he decides to go back being an outlaw with the rest of his team joining him much to Hobbs' disappointment. It is then revealed that what Dom gave the Secretary of Defense was not the real God's Eye, but a music video featuring Roman. It is then revealed that Dom had the real God's Eye and uses it to go on his next adventure with him and Brian discussing where they should go next with Letty telling them to "let fate decide".
-In a post-credits scene, it is revealed that Shaw had survived the rubble and is in a room with four other people who revealed to be past villains of the franchise, Johnny Tran from the first movie, Carter Verone from the second movie, Braga from the fourth and henchman Zizi from the fifth. A mysterious woman (said to be a possible cameo from Charlize Theron) then walks in telling them to get to work indicating that they were assembled to take down Dom, Brian and their crew.
These were interesting ideas but I felt that the final result of Furious 7 worked better, but that ending would been interest hadn't Paul Walker died, but I guess we'll never see these idea come aboard for the next instalments.
