We got 3 kitsune and no one of them looked like these popular kitsune masks. Why don't use this concept now if the have the chance?
I love when they make more creative designs too, but we all know that would give detractors reasons to hate them too. When this happens they usually misunderstand the design and they acuse Game Freak to be uncreative or to make shitty designs too because they aren't for their limited tastes. I'm fine with both kind of designs and ideas, I think it's fun when we got diverse designs even when they reused a concept.
