I wanted to gather all my ideas of the ROTJ space battle, though I know I've mentioned some of this before. I don't have a specific play by play in mind yet.

Several ships should crash into the Death Star shield, as mentioned by Jambe Davdar in Returning to Jedi:

B-wings don't disappear after dodging the Death Star shield

More cockpit shots, both from deleted scenes, and likely from filming new shots as well, including representation from other races, species, and the majority of sexes (meaning newly filmed females as well as redubbing the female pilot's voice (probably a British female, as Bingowings once suggested :). Also it might be cool to see the two person Y-wing cockpit at least once, but I know how people here feel about the EU.

Other ships, including Naboo fighters, BTL-B Y-wing (I personally thought these were pretty cool from the CGI Clone Wars show), Z-95 Headhunters, Aggressive ReConnaissance starfighters (X-wing-type ships from ROTS), Victory-class Star Destroyers (I'm bummed the PT never showed these and instead invented a different kind of older destroyer), more TIE models (especially the bomber), though I am completely opposed to any of the ridiculously overly-powerful TIEs from old video games (i.e. TIE Defender, Phantom TIE), etc. The idea would be to show the Rebels as a montage of whatever ships they could get their hands on while the Empire has a large fleet at its disposal. I know many will not like some of these ships, but it seems like a really good idea to me.

Jerjerrod would be told to destroy Endor if the generator were destroyed, and he then prepares to do so in order to increase the tension, like the clock is ticking and down to mere seconds.
