This sounds cool悪の女神 said:You don't need a Camera to "easily" make a Mii, you can also use a QR-Code.
Here's one I made a while ago of a popular meme:
This Mii is not based on anyone, just that Awesome smiley.
Go to Mii Studio > QR-Code.
Simply point your 3D camera to that QR-Code, and the Mii will pop-up.
