The "more convenient official download" is exactly the reason I'm asking "Won't this get you in trouble"
I mean do whatever you want, I do like having an official polished version of these levels, but know you're playing with fire here.

dont think so, these levels were included in the base game for the longest time and we never got in trouble, the former creator even emailed nintendo about the game and they stated they were okay with it, apparently. But anyways these level packs are pratically glorified json files, nothing really copyrighted there.
