For fanfiction readers this is nothing new. There are dozens of stories that make Lucy into one kind of Dragon Slayer or the other, most times a Celestial or Cosmic Dragon Slayer.

Personally I think the concept is not a good one, since neither is an element. What is a celestial Dragon supposed to eat? The stars? Celestial Spirits? But then the same is also true for Sting's White Dragon Slayer Magic...
