I would be concerned that going from 5/16 inch to 3/16 inch may be too much of a difference to assure that the screws have enough thread engagement. I would think going to 1/4 inch would be a better choice.
This sounds like a simple problem, and the real cause is that the holes were not tapped deep enough, or that the tap had become worn at and was not noticed in time - so several assemblies slipped through with inadequately tapped holes. This may be a problem for a few, and not a universal problem. Yes, the easiest disassembly is to remove the PA unit. Not a major chore, but yes, it is not trivial to get to those screws.
