They don't need Luke for that...
This battle will ultimately be fought in space... Luke can do a lot with the force there, but Anakin is going to be a lot more useful because he's a pilot... The Death Star is going to be what makes SW win here. The Death Star especially the second is huge, can fire fast and several times in a row.
And then there is the fact that SW concentrates far much more on war then ST does. I know a lot of you people are saying yeah but ST has stronger weapons and stronger shields... Seeing as we have no idea about how powerful either one of those things you will just have to use logic
- ST 300 years of space exploring with minimal fighting
- SW several thousands of years of full out wars.
Now which side is naturally going to have the more powerful weapons and shields? Then there is the pure size of the Super Star Destroyers, even a normal star destroyer is already half the size of a borg cube, a SSD is four time as long.
We can debate about technology all we want, but we don't know what it will do. The shields Star Wars uses are to make sure nothing and nobody can get through, not just attacks but entire ships as well. Maybe some ST technology could make them reach the other side but maybe not.
I once saw an episode where those guys were beamed up from a planet and combined or something I don't know because of some plants they had (something like that). Meaning that they are actually still matter as they are teleported. Things like that can not and will not penetrate the Death Star shields.
Then there is the borg maybe they can cut through if they survive the constant attacks from the SD's and SSD's and the Death Star. But again I doubt it, has anybody seen a reason for it? Oh and BTW SW has a lot of different weapons on ships, a lot of them, just go to the starwars.com databank, look at the primary weapons of every ship... The reason you never hear about them is pretty simple why would a captain of a ship like that care about it?
Just shoot the damn weapons and destroy the target thats what his troops are supposed to do, he has no reason to know all those weapons. Something goes wrong? Well great send a repair crew. We are being boarded? Well Damn, now where did I put those commando's. And he sure as hell doesn't have a reason to know the name of everybody on the ship.. A ship thats 12 kilometers long is to big for you to know by heart and far to big for you to know everybody in.
Also you have to remember that a movie in SW about just one ship would be damn boring because we would miss most of the mayor wars going on, and all the fighting that they constantly do. In ST what would you miss? Well mostly nothing because there isn't really any fighting. Thats why SW would win. They fight mayor wars when ST does not.
Pretty long post to get this away from Luke
