Okay, so I'm currently working on Yag'Dhul (at the time of this post) but, I thought I'd address why Jakku is a very unlikely candidate for the mod.

"The Galaxy Awaits" is set in a controlled bubble of Legends/Canon where the first Death Star WAS destroyed but, Tarkin lived and Yavin wasn't invaded by the Empire post-Death Star destruction (yet).

While Jedha is a possibility, for suspension of disbelieve, if we were to add it, it won't be a crater like it was in Rogue One. The same goes for Scarif. One plus side of this would be that subscribers of the mod will be able to send Kyle Katarn to do the job of an entire squad ;D

Hosnian Prime is already on the table as a potential new planet for the mod since we know where it is in the galaxy. It will be taking Duro's place on the Corellian Trade Spine and Duro will be moved closer to Corellia.

HOWEVER, Jakku is a different story completely.
The Battle of Jakku is set at the very end of the Galactic Civil War.
So even if we were to include it, there wouldn't be the valley of crashed Executors and SDs like there was in Battlefront and Force Awakens.

Jakku would just be a "middle of nowhere" planet with lots of sand dunes.

One possible work around for this would be if we were to create a second campaign with all of the planets this mod currently has but, have it set in the final months of the Galactic Civil.

For example...
For the Empire

• Palpatine wouldn't be available
  
• Tarkin wouldn't be available
  
• Piett wouldn't be available
  
• Veers...might be? He didn't die so...
  
• Vader wouldn't be available
  
• Boba Fett wouldn't be available

The Empire would however get 2 or 4 Executors and Thrawn to make up for the lack of heroes.
The Rebels would get pretty much everyone except Yoda and Obi-Wan.
Essentially, Thrawn's Revenge mod lite except grounded in Canon more than Legends.

As much fun as I would have making Jakku, I wouldn't be able to look past the continuity error of post-Galactic Civil War Jakku being present in the mod. Maybe years down the line but, not in the near future.

I really...REALLY want to make Vardos but, it doesn't have a confirmed coordinate on the Galactic Map yet :c
HOWEVER...I could guess that it could be placed near Duro or Corellia because...

--SPOILER--
In Battlefront II, Resurrection, you can see Starkiller's laser hitting the Hosnian system from the ground on Vardos.

So...Vardos might come to the mod in the near future.
In fact, I might even put working on Yag'Dhul on hold to work on Vardos c;
