Actually, cheats are physically incapable of doing something like this. Codes generally have two parts: something saying what to change, and another what to change it to. This means it can edit data values like how many rare candies or money you have, but something like switching an image is way beyond it and would require using hacking software on a rom and adding in custom images. Something even as simple as changing the dialogue of a pre-existing NPC would take hundreds of lines of code, assuming it were possible at all. It can do things like graphical glitches and create horrid audio, but that's usually a result of poorly written code telling it to access data that it wasn't supposed to.

Don't believe me? Just try to look up codes that change the way the game looks. If you're lucky, you can find codes that make an object use the sprite of a different object, but it everything involved would use images that were already in the game.
