Sounds like a mix of the Star Wars Galaxies MMORPG (Discontinued), the RTS Star Wars Empire at War and the Playstation 2 FPS game Battlefield 2: Modern Combat. Star Wars Galaxies allowed players to choose any job they desired, If they wanted to be a musician or dancer they could earn money by practicing their art near players and receive tips. The player could choose to join the empire or rebellion factions and acquire set pieces that helped them look the part, or they could be bounty hunters searching for players with a high price on their head. The options were near limitless and if a player wanted to be a Jedi they would have to complete rigorous tasks and puzzles to find a lightsaber, the Jedi players were always hunted.

Star Wars: Empire at War has a lot of Star Wars-esque gameplay elements and features space combat along with battles on the planets surface. Controlling certain planets gives you huge advantages such as owning Kimono allows you to use their clone facilities and create soldiers costing a minimum amount of resources. There were also hero units like Boba Fett or Han Solo with options to use their ships in space combat.

I mentioned Battlefield 2: Modern Combat because its unique feature in single player allowed the player to swap to another soldier anywhere on the battlefield, If you were on the ground but wanted to fly the helicopter with just one button press you were piloting the helicopter. This 'hotswap' feature was amazing and I don't think I've seen any other FPS attempt this in real time. I hope your wish comes true, it's going to be amazing to play. Thank you for sharing!
