The problem with using transfiguration sickness as a threat is that LV possesses the Philosopher’s Stone and can easily make a transfiguration permanent once he notices it.
A better option would be to transfigure a massive dose of Ebolavirus in the Death Eater’s bodies. It will be deadly if made permanent. Once given a chance to reproduce, cancelling the transfiguration won’t save them either.

This seems kind of reckless even for Harry.
That all depends on what the traditional Death-Eater burial practices are like, and if they can be induced to change them.
