Idea for Final Destination 5?

I had this idea for FD5: Its like the movie is set in a city and that it takes place in a very near future like 2020 or so that the city is protected from getting washed off by walls that keep the high sea level from coming in. So my idea is there is this guy (lets just call him Derek) who has a premonition of the sea walls collapsing and the water destroying the entire city. Then when he wakes up he quickly rushes to the sea walls and then the walls start to crack and makes a loud sound that evry1 panics and then Derek stops it just in time (like increasing the pressure in the walls) and then evry1 celebrates but then evry1 starts dying IN GROUPS like in Airplane crashes and Subway derailments and Mall Explosions or even Pile-Ups, referencing the last 4 movies (of course the gore stays =) ). Then in the end Death has start to make deaths that are impossible because Derek keeps intervening deaths but has not enough time to stop other deaths so then in the end Death decides to set down several Tornadoes on the city and everyone dies except Derek and a few others who got to a Boeing 787 just in time and escape the city, narrowly missing tornadoes and debris. THen the ppl on the plane sighs but then Derek sees that the plane number is "180" and there is a poster witht he phrase "This is the end of the line" and then Derek sees visions of The Flight 180 explosions, the deaths, the route 23 pile up, the devils flight roller coaster derailment, the subway derailment, the mckinley speedway incident and then finally he sees a vision with all the survivors who died in the last 4 films (Alex, Clear, BIlly, Carter, Terry, Ms Lewton, Tod, Kimberly, Officer Burke, Rory, Evan, Nora, Tim, Kat, Eugene, Brian, Wendy, Kevin, Ashley and Ashlyn, Lewis, Frankie, Julie, Perry, Ian, Erin, Nick, Lori, Janet, Hunt, The Racist, Andy, George, Nadia, Jonathan and Samantha), staring and surrounding him and then a lightning flashes and during the lightning the survivors in hell has their faces flash their skull and back and vice versa. THen when Derek snaps back to reality, the left side of the 787 blows up in a similar fashion as in Flight 180 and then the plane explodes. While Derek is burning, Death appears to him and says: "I win" and then Derek dies. So tell me what you think! =D
