Hey, its Zachary here, coming at you live from V.A, and I'm awesome at Halo, MNC, and WaW.
I had an almost identical thought!!! But here are some changes that make mine different from yours: Before you get in the HEV, you start in an armory, and it stores every weapon. But not like a bunch of Rocket Launchers and Lasers, only a few of them. Now you can go right, to the HEV Pods, or left, where you enter the hanger. In the hanger there are Falcons, Pelicans, and one Longsword fighter. (however, the Longsword never respawns) You can use any of these. the Pelicans are fully usable, meaning that you can pilot, ride, and shoot out of them. And also, some of them have different types of Warthogs that you can drop off at strategic points on the battle field. Also, you have a MAC gun, however, you can only fire it 3 times per round.Thats it. My idea for multiplayer. Like or not, tell me by messaging my gamertag, Slashing Hard.
