I know it's an old thread but i happened to be reading stuff about generations today and found this old thread on my search so i thought i'd add something.
If I was in the movie business, i'd of made a sequel to ST6 as ST7 and done generations as a standalone first movie for TNG but it would've been different.
ST7 would've had the Enterprise A returning to space dock after they headed off at the end of ST6, where the ship would be decommissioned and the crew transfer to the newely unveiled Enterprise B which then goes out on it's maiden voyage but with the same captain as generations and crew but all the stuff that followed the tuesday joke but be already in place, the ship would be fully working. They would encounter an energy ribbon but there would be no nexus and no one would die, apart from one of the transport ships. There would still be a dr soran and instead of the nexus thing, he'd be found out to be working with romulans on a weapon to destroy a star to wipe out a star system. romulan agents are on the surviving transport which breaks free but is damaged, they are altered to look human and they steal a shuttle with soran and disable the enterprise b engines and shields to escape. The crew don't find out who dr soran is or what he's planning till they board the damaged trasnport and check the logs and computer in his quarters.
Kirk, Chekov and Scotty would be on the first voyage as guests. Kirk now an Admiral, Chekov and Scotty a teacher at the Academy.
stuff happens...
at some point the captain gets injuried during a battle with a romulan warpship and kirk takes command briefly.
more stuff happens
movie ends with Kirk returning to Earth to test students on the no win simulation, ending with him laughing about a questing from a vulcan student who asks him how he beat it. "you may ask..." queue raised eyebrow and end credits. no lame bridge death.
Sulu would also get his own movie entitled Star Trek Excelsior : The Klingon Way or some other catchy name, to come out shortly before or after ST7. (kirk mentions sulu's ongoing mission in klingon space)
Sulu invesigates a klingon consiracy involving the destruction of praxis and the future of the klingon homeworld.
which evntually turns into a tv series after at least two more movies, making it a trilogy. with an episodic format where sulu hands over command to his daughter from generations.
star trek generations still gets made but is entirely tng cast and no nexus. instead it's starts off with picards family tragedy and then a klingon plot by the duras sisters to kidnap geordi so they can get some secret starfleet intel on a recent mission where the enterprise found dead romulans on a startfleet observitory. They were devloping a weapon with the klingons to attack starbases along the netural zone. hybrid klingon-romulan bird of prays with cloaking devices and they could fire when cloaked, they need to erased that intel which hasn't been decoded yet.
they use a mind control device to make la forge go to a computer terminal and wipe the data
how did they kidnap him? he was coming back on a shuttle from the observitory and the klingons intercepted him, knocked him out, wiped his memory of the event and put in the mind control deivce which they triggered while cloaked following the enterprise.
they wipe the intel and la forge is knocked out again by the device which is discovered, data manages to detect the klingon bop and they have a battle but the sisters escape.
later the star bases are attacked, the enterprise arrives, there is a massive battle and lots of ships are destroyed, klingons and romulans surrender and the durus sisters ship is destroyed.
