The game is so big on maintaining a set timeline, but it already doesn't pass the fluff test as you can have biggs flying escort with a kwing...
No to mention having rebel on rebel, imperial on imperial, etc matches doesn't make sense either.
I think the game is fun enough that they should just throw the timeline out the window, and just make it a fun game with multiple factions and ships.
It's been done before in video games like galactic battleground and battlefront.
Just add 4-5 new factions: republic, confederacy, resistance and/or new republic, and first order.
If players are against it (like some are currently with scum), they can just stick with rebels and imperials.
