Oh, so now we're indulging in frivolous what-if scenarios in order to defend our thoroughly indefensible propositions, are we? Typical. But I will match your fictional hodge-podge word-for-word and lie-by-lie, never you fear...
I take issue firstly with your assertion that Dumbledore would allow the students to, as you so aptly put it, 'run wild' in a teacherless environment. He would not. As proved on many occasions, our favourite Headmaster is not above the occasional bit of blackmail, coercion or downright sorcery in order to fill a post; cough Slughorn cough. :P However.
Even if we accept your ludicrous imaginings, your argument is as self-defeating as it is risible. If Hogwarts is now packed to the pointed tip with 'Transfiguration masters', what's to stop them transforming Voldemort, Bellatrix and their army en masse into sixty-four darling baskets of soft, mewling kittens? (Kittens with anger issues and the occasional murderous impulse, yes, but kittens nonetheless.) I hardly need remind you that the manus of a cat is not suitably designed for waving a wand; henceforth the Death Eater threat would be eradicated. McGonagall has, in her absence, proved to be thunderingly inessential and peace is restored to the wizarding world. Also, more kittens, and kittens are made of win. So there.
Now a cupcake, please. I feel I deserve one for so kindly pointing out your logical shortcomings. :P And as to whether you'd stand a chance against Ron... really, now. You know full well Hermione would track you down inside the week and beat you slowly into the cracked and dusty radioactive wasteland that was previously your family home with a short thick stick and a gigantic metal spoon.
