I don't think this is likely, if only because of the unsatisfyingness. However:

And the messages would come out in riddles, and only someone who heard the prophecy in the seer's original voice would hear all the meaning that was in the riddle. There was no possible way that Millicent could just give out a prophecy any time she wanted, about school bullies, and then remember it, and if she had it would've come out as 'the skeleton is the key' and not 'Susan Bones has to be there'. (Ch.77)

Some foreshadowing on the idea of ominous-sounding prophecy terms actually referring to people's names.

Beneath the moonlight glints a tiny fragment of silver, a fraction of a line... (black robes, falling) ...blood spills out in litres, and someone screams a word.

"blood spills out in litres" meshes well with "TEAR APART".
