I was wondering If it is even possible to add the republic and separatist drop ships on one of the maps. I was thinking about this for a while, but I think I have a neat idea to pull it off.
First off, I have NO MODDING EXPERIENCE AT ALL!

I was thinking if it would be possible to have reskinned pelican and phantom drop ship to resemble their respected star wars factions.

For the republic drop ship, it could use the Halo 4 pelican design since it's cockpit windows look almost identical to that of the LAAT/i and having two gunner seats on the sides of it as well. The pelican will also have the iconic white and red republic color scheme, and for its primary weapons, it will shoot out the ghost plasma bolt shots (with duel firing like in halo 1). I also think the Pelican's primary weapons should have the damage output the same as the ghost so there is no real rush to run for it other then to have some good air cover to support ground troops without being too much of a beast like in the original battlefront. It would basically be a flying ghost if you have no co-pilot, but to get the most out of it, you would want to have a co-pilot.

The secondary weapon would be a co-pilot function which be the green laser beams that the LAAT/i dropship has. They can be placed on the very end corners on the wings of the pelican you can have turrets that fire out sentinel beam lasers, if that is even possible. To add some star wars friendly coloring to it, maybe the plasma bolts and sentinel beam lasers be changed to green to make it complete, despite it being a reskinned pelican. Also, the Pelican needs to have vehicle health added to it so it can explode like the phantom, that way it's not overpowered. Maybe the pilot's hud can show the health bar for both the phantom and pelican.

For the separatist drop ship, the Phantom can have a black and red color color scheme, and be a single pilot drop ship. The plasma cannon gunner seats could be sealed up replaced with the Halo 2 styled phantom with the 3 plasma cannons(if possible). To balance the 3 turrets, the two back turrets can actually be operated by other players by making them a vehicle of their own that the player can enter.

For the projectiles on the phantom's turrets, they can use the regular red sentinel beam lasers, no color changes needed since they're already an orange red which would fit the separatist theme. The pilot can operate the main front turret that is under the nose of the phantom, which can keep the plasma shots it normally fires but the color of the projectile can be changed to pure red. Maybe slow down the fire rate and make the splash damage of the projectiles have a fairly decent radius upon hitting the ground. Maybe after every 6 shots the main gun overheats and has slightly long cool down. This way you would want to have two people as your gunners. If the Phantom is destroyed, that is a damn good triple kill.

Let me know what you think, I just want to know if it is entirely possible.
