No, otherwise a plothole could ensue. Say you managed to capture a Bakugan in a previous unlocked brawl. Normally you should have that Bakugan with you as an option to battle with in the next one, but if the brawl is not locked, the Bakugan won't be transferred. Creating a problem. And since it is invalid to use a Bakugan you seemed to have claimed without it being in your profile due to the fact that the brawl you won it from may have errors within, begnining multiple brawls while waiting for one to be locked up isn't wise.
