Well, you could do a full memory hack, but that's clearly a lot more work than you're willing to undertake. lol No one's going to blame you there. You'd have to edit the tile data, the sprite layout data, the hitbox calculation data (if they used hitboxes) or the whip length data (if they didn't use hitboxes), and likely some other stuff. Naturally, first you'd have to find the locations of all that stuff in the memory. It's not impossible, just a lot of work.
