So I’ve done ports with a reinforcement where I’ve basically laminated that area, but what would be the downside in reinforcing it with epoxy and a fiberglass mesh?

Probably lots of ways to skin that cat. I have seen guitars that just had a hole drilled in the side without any reinforcement and it worked fine. CF plastered on the inside with epoxy would help prevent cracks from originating at the hole. But I agree with Ed that it might not be the best look. I laminate a piece of side cut-off, bent to fit, to make a cross-grain patch inside. It can look good if you sandwich a contrasting veneer in the middle which gets revealed as a ring at the opening, and can tie into your purfling scheme. Binding the hole looks classy too, and affords extra protection to the rim.

I'd prefer cut out a soundport backed with just about any wood rather than fiberglass.

If you are binding the hole no one will notice. If they go looking inside with a mirror they will see it so if you choose that route, just do a clean job of it.

I laminate cross grained wood and bind the hole. It looks good and works well.
