How to reset default Minecraft skin to Steve?

I liked the Steve skin, but then the default skin was set to Alex. I don't mind Alex, but I want my default set back to Steve. When opening the MC launcher, I changed the skin to the Steve skin file that is in the MC assets folder. This gave me the Steve skin, but it treated the Steve skin like a downloaded skin, not a default. The problem with this? It didn't work with texture/resource packs. For example, I have a Gravity Falls pack that changes Steve to Dipper Pines. But when I have the Steve on, it won't change to Dipper!! Any advice?

Woops... Just found it out myself... Apparently you can't change your default, because it's randomly decided based on your account ID...
