It's an interesting idea, but in all honesty, YE really works in the context of a larger show with a fan base. In other words, YE only works best if you're a fan of ST, familiar with its history -- the fact that several Starfleet ships bear the name "Enterprise."
Surely, some of the ideas posted in this thread are superior to the movie we got, GEN. And I agree TUC was a good send-off for the original crew, and too bad it couldn't have stayed that way. Then we wouldn't have gotten Kirk's lame death, or the lame destruction of the E-D.
Although if we did superimpose the main plotline of Y-E and had the E-A having to go back in time to face its destruction to preserve the timeline, how cool and dramatic an ending to Kirk & Co. would that have been? Of course, you would have had to keep Spock, McCoy, & Scotty off the ship to conform with the later TNG eps featuring all three.
