Obviously its gonna happen. The other sannin have "picked" their kid from kakashi's team, and sakura's useless now, but she would make a damned good healer, due to chakra control, and always running to sasuke when he breathes heavily.

Plus, sasuke and naruto are mainly close up fighters, that damages them the most, as it is now, fighting style wise... they have a pretty unbalanced team, and a decent healer would straighten things out a bit.
