Due to a comment from someone about this being "texture ripping and against TOS", I took some time to speak with a friend who is quite familiar with such issues.

While she concedes that it could technically be a grey area, it's not something that has been defined as specifically against TOS.

The problem comes in if someone decides to start SELLING the appliers they've made with this - then yes, you'd be selling someone elses textures and that would definitely be against TOS.

So please, don't be a douche.
