New way to make Minecraft skins

I love how simple it is to make a custom Minecraft skin, but an idea came across my head. What if we were allowed to size our skins? tall, short, thick, thin. Without stretching pixels or different sized ones, or mixels as some people call it. We already have the choice between Classic & Slim. So this would be a great way to be even more customized! Best example of this would be Axel from Minecraft Storymode. I always loved his design!
