I just discovered that in the iOS version of the game, all of the unlockables, including BB-8, R2D2, and Mace Windu, are all available for purchase with just sparks. Although some of them do cost like 50,000 sparks. But the enemy unlocks were quite cheap. So maybe it's not really necessary to go out of your way to get all gold on the challenges and all the mission stars.
