While it's not impossible as such, it is rather unlikely.

With Elie we got a lot of hints about her powers from the start and then an outright confirmation when it almost exploded (after Siegharts torture) and Haru sealed it last minute.

With Lucy the only hint we ever got of her having any relation with the One Magic was that one talk with Capricorn which didn't even last half a minute.

Thus I doubt that we'll be seeing Lucy wielding the One Magic or being powered up by it anytime soon. Maybe later but I seriously doubt it'll be soon.
