Entirely baseless speculation that almost certainly won't happen but will make me look like a genius if it does:
Stage starts off with platforms high in the air, with the ground shown like the screenshot, in that retro style, below. At points, the platforms descend to the ground, through clouds, and at the end of the transition you come out and battle in a section of that map that has been redesigned to look full 3D, and HD. Basically a moving stage blending a retro stage with a new interpretation of it.
