Maybe a large space battle could be an idea. Not only consisting of the ships of the Roleplayers, but also numerous cruisers, fighter squadrons, frigrates, capital ships, all send by the supporters of both the Jedi and the Sith. For example: The New Republic sends numerous ships as an escort with the Jedi, and the Sith, who want to invade the Jedi Temple, bring ships as well from their supporters to be able to smash through the defence of Coruscant, which is loyal to the Republic and the Jedi. Everyone meets somewhere halfway, and a large spacebattle comes to be. These fleets could be commanded and used by the Jedi/Sith Masters/Knights/Padawan(?). Because no-one really plays any of these characters (imagine captains, crewmen, squadron leaders, etc), they can be fought, fight with you, killed and be killed without any Roleplay-troubles. This will make the battle more realistic, for if no-one dies, it isn't very real, is it? And in the end, our ships crash on some kind of planet, and a ground battle starts (maybe even with ground forces (troopers, tanks, speederbikes, artillery) but that might be too much of the good thing
)
Just a small idea of mine
