I think this theory is cool, and sort of hope that this is what happened. But... Dumbledore says he felt a student die. Whatever magical detection he uses for this probably wouldn't trigger for Polyjuiced McGonagall.

I bet the Deputy Headmistress can enroll students at will.

Unless she told him what her plan was before he encountered harry.

What about Transfiguration, which is what davidchart talks about? If you are literally becoming another copy of an existing student, perhaps this interacts with the wards differently than merely drinking a potion that alters your appearance.

(Yes, transfiguring yourself into another living being is fatal, but not straight away, and this is a suicide mission)

Mcgonagal would have to have someone else transfigure her, or else the spell would end when she dies. (Perhaps dumbledore? Not sure he would go for it.) Polyjuice would be another approach, but it wears off after an hour, so dumbledore would have to do another body swap after Hermione/mcgonagal is killed. Again, not sure he would go for it. Who else? Quirrel might be desperate enough. Snape is loose but I don't see him going for it.

So several things would have to fall into place but the plot buildup is definitely there.

Wasn't there a story about someone who accidentally Polyjuiced herself into a cat and, instead of getting help, hid from the teachers, so she got stuck cat-like? McGonagall could turn into a cat and Polyjuice herself into Hermione from that state, to get the effect deliberately. The waxy, doll-like appearance could be a side-effect of deliberately botched Polyjuice. Or... Hermione could Transfigure McGonagall. Hard, but quite possibly just within her capabilities, with guidance.

The ward message is a problem, but, as jaibot suggested, maybe McGonagall enrolled herself as a student. Or maybe the wards sound the same for students and teachers, and Dumbledore interpreted it when he saw "Hermione" dead.

The description of the death scene is Harry's interpretation, not objective truth.

At this point in the narrative, I can add epicycles to deal with the problems, which is just as it should be. It is a beautiful theory (and my baby!), and I still have a few hours before the really ugly facts show up.

Edit: And here they are. The tragedy of theories strikes again…

My condolences. It really was a nice way to save Hermione.
