Yes, the key here would be to make the holes large enough that the flow through would exist throughout the intended use velocity. I have considered making a mirror my polishing some perforated steel. It would be very labor intensive to get it up to mirror shine. It would give you a "flies eye view". Your brain would need to fill in the blanks.
