That's already a thing, fyi. Thingyfy sells them.

The problem with pinholes is that doing macro shots is nearly impossible, let alone doing micro shots. This is because each pinhole size and focal length has a minimum distance. So, the closer the subject gets to the pinhole the blurrier it gets when it reaches that minimum distance. Also, the light cone can't expand far enough to give you the macro or micro you want with short focal lengths since there's no lens to focus. You'll also end up with an image circle so small it'll be a dot in your photo. The best you can hope for is to use a telephoto pinhole and get something closer to it. It will be blurry, but also macro. Making a longer one will do micro, but it'll just be a blurry blob. Pic mostly related.

The best thing about that pinhole is that I can crank the ISO a little and go handheld with it at 1/40 or faster exposure.

This device is also a pinhole. The body cap has what I call a "Pinhole Slider Cap". I can make several pinhole diameters that work at different focal lengths. Then I can mount it to my macro bellows and have a zoom function. In this image, I've taken every single extension tube and bellows I have, connected them and put a pinhole on it. The two photos at the bottom show what a regular lens sees and what the super pinhole sees. Terrible quality, but fun to setup.
