More Sonic 2 sprites in sonic 3k

When running up cylinder objects like the tree in Angel Island, Carnival Night, and Flying battery, sonic uses his sonic 2 sprites. Some of you know that sonic uses a design closer to his Sonic 2 one in flying battery when on the chains(I don't what they're called...). What if I were to tell you that there is another place where this happens and I have heard no one talk about it. In competition mode of Sonic 3 or Sonic 3k, if you jump, he switches to his sonic 2 sprites, you can pause and see that they're stripped from sonic 2 just bit crushed. I know this is pretty minor but if you really look in games or something else, you'll find something that no ones talked about in person, online, or somewhere else. 

Edit: Can someone make a mod where it replaces the sprites with the sonic 3 ones just cropped to the same size?
