Ooh, some fun ideas here! :-)
How about (and this is drawing from everybody's suggestions) two large ships, one Covenant and one human. Each one is pretty big, and each has a hangar with various ships (Banshees or something like them for the Covenant, and who knows what -- Longswords? -- for the human ship.)
There are windows at various places on the ships, but they're pretty strong. A little plasma rifle shot certainly won't break it, but something like a rocket launcher -- or, for example, a Banshee fuel rod cannon -- could pretty easily blast it open. In addition, there are various external turrets on the ships, which can be used to shoot at Banshees outside or at people in the windows of the other ship. The turrets, however, can be destroyed.
Everyone's equipped with magnetic boots (and maybe that MX-3 thing, which sounds fun). That lets people have a little mobility outside, though they would need to board a vehicle to really get anywhere. As a CTF map, there's a flag in each base. To get across, players need to fly. Or, perhaps they could jump, a la the original teaser trailer.
One potential issue, however, would be how to keep people from just flying away... and away... and away... There would have to be some limit to where you could go, though it would be no fun to suddenly run into an invisible barrier out in space. Maybe the ships could be surrounded by an insanely dense asteroid field, so that if people headed too far away they would be instantly smashed to bits. Even better, the ships could be flying THROUGH the field, so that at any time a giant asteroid could pulverize your ship or turret! :)
