I like the idea of what your doing. However, I disagree with about the show, I was okay with the sideways world. HOWEVER, it should come AFTER Jack dies. Therefore, all the island stuff comes first like what your doing....then at the end of your revised LOST, Jack dies, closes his eyes, then fade to black....wait a second or two, then fade up white with Jack in the plane from Season 6, Episode 1, and then the entire sideways version happens. If your up to it, that's how I would do it....
Thanks for the feedback. We’re going to have to stick with the belief that the sideways world is superfluous, though. Plus, Jack closing his eyes is what brings the series full circle. That moment, actually, is the perfect end. To put anything after it would, once again, take away from the overall story.
