No insult or even critique of your theory. I was just listing a few of my own.

In regard to your theory, I think just beating Kyouka senseless, like it was done in some instances of the past, won't be enough to reverse anything. Considering how the machine is working without any apparent connection to Kyouka, while the she-demon even does something different in another room, I somehow doubt even killing her will do any good for those alreay transformed.

And with Fairy Tail being the good guys, threatening or torturing Kyouka into reversing the process seems out of the question too... on the other hand Erza did the whole threatening act and Natsu even tortured that Phantom Lord small fry once... still I doubt Kyouka would be very susceptible to either.

But even if threatening and torturing won't help (or won't be tired) they could try to read the knowledge of how to work that machine from her mind with either Warren's telepathy or Cobra's hearing.

Alternatively they might arrive in time before the transformation is complete and simply smash the tank. That still wouldn't save Minerva, but who (apart from Raven) cares about her.
