I mean hell, even I largely based my idea for Twilight Sparkle's NP on Unlimated Blade Works, right down to including a chant, which itself was largely adapted from an actual speech Twilight made in the show when first using the Elements. But that's Fate in general, you can see people taking inspiration from it for abilities all over the place. Like that Equestria Girls/Bleach story I was reading, Rarity's Fullbring started out as basically being Shirou's trace ability, then it was Unlimated Blade Works, and the mastered version was a mix of UBW and Iskander's NP (Chapter was even named after his music theme). Kinda happens when your series is loaded with cool as fuck abilities.
