You want enough space to get your hand in there. I'd cut up some of your cardboard boxes & mock up the sizes to see how it would work.
I might do a combination of your idea and @bearisgray's idea because...um...we have bugs in Congo and I couldn't leave the squares unattended. Unless they were in an airconditioned room, moths will find a way. Thank you for the dimensions!
