The soul still persists, I believe, so if dovahkiin's body can be reassembled (and the soul reunited with the body), he can be ressurected with flesh time undo. I think if someone rebuilt Numinex's body, same can be done. Basically, a dragon's soul is eternal, until devoured, but when it is devoured, it is not destroyed, but just mills around in the body that devoured it (that's why when you kill Miraak, you get multiple souls, for his soul counts as one, the others are from the dragons he devoured.)
