The problem with the side (front) seat of the ghost is that you cannot get 2 people in it
It is a good hiding spot though.
This mod's easier to find but it goes along the lines of 2ndary fire on the turret.

Here is the long readme:
HOW TO USE THESE PATCHES:
First off, make sure you are playing a gametype that has all vehicles available, or just the Scorpion available if you want just the turrets.
inject.ppf - INJECT ALL FILES: You MUST use this patch first before using any of the following patches. It injects files that the following mods will try to use. If you don't use this first, your game will just crash. Using just this patch will not create any changes you will notice right away (except for the scorpion being replaced by the warthog), but if you want to make your own mods based on this, this is a good place to start since you can inject the files with this, and then use them as you see fit (ie. making the rocket launcher fire wraith mortars). Below the item and ident numbers for the files will be listed so you can more easily hack this mod.
**************
INDIVIDUAL PATCHES: These are good if you want to make your own gametype since you can pick which mods to use. Make sure to use the injection patch before using these.
turret_2v2.ppf - TURRET 2 VS 2: This places 2 turrets on each base (one on either side of the teleporter).
turret_2vs0.ppf - TURRET 2 VS 0: Only the Blue base gets turrets. This is good if you want to play 'one-way' ctf or just to give one team a handicap.
turret_0vs2.ppf - TURRET 0 VS 2: Only the Red base gets turrets. This is good if you want to play 'one-way' ctf or just to give one team a handicap.
turret_1vs_all.ppf - TURRET 1 VS ALL: This places a turret in the center of the level.
turret_mortar.ppf - WRAITH MORTAR TURRETS: This will change the secondary fire of the turrets to Wraith mortars.
fuel_rod_pistol.ppf - FUEL ROD PISTOL: This will change the secondary fire of the plasma pistol to the fuel rod projectile.
homing_rockets.ppf - HOMING ROCKETS: Gives all rockets homing ability. Your reticle must be a certain distance from an enemy when you fire for them to home in on that person. The rocket launcher only has a one rocket chamber and can hold three rockets maximum now.
warthog_secondary.ppf - WARTHOG SECONDARY FIRE: The Warthog turret gun now has a secondary rocket fire (yes they will be homing if you used the homing rocket patch).
bomber_ghost.ppf - BOMBER GHOST: The Ghost now flys and drops frag grenades from above. Excellent for taking out those that are trying to just sit in the back of a Warthog shooting homing rockets (the Ghost is able to outrun homing rockets).
camera_man.ppf - CAMERA MAN: There is now an invisible camera man in the small nook on the shady blue base side of the level. You must have a trained version of Halo so that you can 'bump' him to become the camera man. He can fly and has no HUD. He is excellent at taking screenshots and movies. Don't worry if he dies, he respawns. As a side effect to this mod, the pistol reticle is a little different (set to rocket launcher reticle), and the pickup icon will be a rocket launcher. (Don't pick up any weapons as the camera man as he will then have a HUD)
**************
DEFAULT PATCHES: Here's the defaults I have picked out for you. These are nice and easy, and should provide a good start, but hopefully you will use the individual patches to build up your favorite gametype. And make sure you use the injection patch first before using these.
slayer_carnage.ppf - SLAYER CARNAGE: This is almost all of the mods rolled into one. Two turrets on each base, homing rockets, fuel rod pistol, Wraith mortar, Warthog secondary, and Bomber Ghosts.
bombing_run.ppf - BOMBING RUN: The Blue side gets homing rocket shooting turrets, and the Red side gets Bomber Ghosts.
impossible_ctf.ppf - IMPOSSIBLE CTF: Each side has two homing rocket shooting turrets.
