multiple pinholes?

Hello:

Weird thought:

Pinholes, I read, have none of the optical aberrations glass is plagued by.
Resolution is low.

With a lens, symmetry (dual elements about a stop) cancels much aberration.
Alignment and coverage would probably be challenging, but would there be any
advantage to a 2-element pinhole?

Not two next to eachother, but one looking thru thes econd.

Thanks

Murray
