If this is like promotions some years ago, it's your most recent preference that controls. If I recall correctly, some folks posted that they finished qualifying for their MegaBonus and then switched over to the miles promotion and did that one.
So, I don't know whether you can switch back and forth, but I'm pretty sure you can't use the same stay for both promotions.
