Not all of the parallax could be recreated the same, but otherwise, DKC has less action, sprites on-screen, animation, etc, that Sapphire has. A straight port would lose shades of color, but a customized version could add more color in other places. Pretty much any of the 16-bit consoles can do versions of any 2D game from another console. They just need to be rebalanced to match the new hardware.
