It's a theory. I highly doubt it, but it's a theory.

I just can't see that happening though, because firstly we don't know the extent of Shini's powers. We're not even sure if her magic (or hypno stone) can even mind control more than one individual, let alone the entire Hamato Clan simultaneously.

Plus, she was seen on the far left of the allies part of the "Good guys win and the bad guys lose" part of the intro, along with Karai. So yeah, I'm pretty sure Shini is going to be a prominent ally to the turtles.
