I guess you're not all too present on FanFiction.net. You'll find plenty of stories about Lucy either meeting a Celestial/Heavenly Dragon or being such a Dragon Slayer from the beginning with that part of her power and memory sealed up. And instead of flames, shadows, iron or whatever she's shooting stars, galaxies or black clouds with stars and galaxies in them.

Personally I think the very concept of a Celestial Dragon stupid. It's bad enough to have both immaterial elements like Fire and light alongside materal elements like Iron or Adamant, but what element is "Celestial" supposed to be?
