The "Sliding Doors" Lost Theory

I was reading a Q&A with the Lost producers, Carlton Cuse and Damon Lindelof, and a new Lost theory popped into my head. Cuse mentions in the interview that season 6 uses a different narrative device than what we've previously seen (flashforwards and flashbacks). So keep in mind that the biggest question going into season 6 is if the Jughead plan worked? ... what if the new narrative device will be showing us both time lines at the same time?

Now, I know that this could get confusing, but it worked in the movie "Sliding Doors," hence this is my "Sliding Doors" Lost Theory. With this type of storytelling, you could satisfy both audience segments, those for a time line reboot and those against it. You could tell what happened if the Jughead plan didn't work and show Jack and company either dying during the incident (as Richard Alpert said he saw them all die) or living on in 1977, and at the same time, you'd have the time line of 815 never crashing and seeing what happened to everyone once the plane landed in L.A.

I'm not sure how'd the entire season would play out like this, but it would be an interesting way to see both sides of the story.
