Very funny thread. I do seriously wonder though what it would've been like if Picard were in this film instead of Spock though - it'd have been like a passing back of the baton, and I think a lot of today's young viewers were more familiar with Picard - "the bald captain" to the layman - than the pointy-eared guy, so you got the symbolism of a new era there. What if he'd died? It'd be a very moving sendoff, moreso than Nemesis (hell, if he were just in the movie anyway it'd still be better than Nemesis).
I don't doubt that it could work. But as I mentioned before, it would prove all that dramatic as well as having Spock-Prime there. It provided that link to tie certain things together.
