It’s possible, I suppose. I don’t think Flamel is intended as the villain, though. If he’s just evilly suppressing immortality for the masses, then Harry will kill him and take his stuff. Seems like the Stone being an interesting aside and maybe minor McGuffin, along the level of it’s importance in Canon, rather than rendering the main plot completely irrelevant.
