List building happens simultaneously, it's not a step by step. So when you add/remove something that makes something else illegal, then you can't have it anymore. Just like how when you add something that is now legal. During the game you're past the list building phase, so everything will stay on you unless a game effect removes them.

Example: Maul's need to have Ezra when doing a rebel fleet. You build a list that has ezra on the attack shuttle, and maul on the YT-1300. You then decide you don't want the ezra attack shuttle, but the zeb attack shuttle. Although you've already added maul to your list, you can no longer have him, because Ezra is no longer on your list. If you were to then put ezra on the attack shuttle as a crew, you may re-add maul to the YT-1300.

Hopefully this clears it up.
