A couple would be awesome, such as the gunships bringing in troops and capital ships firing down, but I think the way of achieving them should be different, or else in singleplayer the AI would just get dominated.

This would be beyond awesome, and imagine if they got seamless ground->space in as well! Huge 256 player battles around Coruscant, and in space it'd be chaos!

Something I can only dream of though.

For a start the MAG game could just be given a Star Wars overhaul.
