Face paint idea

I just thought I could post this here to see what other people think. Too many times I wanted to use both eyeshadow AND blush, or just blush and a mark on my forehead. Wouldn't layerable face paint be awesome? I don't know if it would be possible, but something like two layers would do. I really love character customizarion and I think it could bring it even further. What do you guys think? Would it be possible for SE to offer it?

They've mentioned due to memory and stuff that they can't right now? I might be wrong, but I love this idea and hope one day they can do it!
