What would *I* do?
1. I'd stop looking at it.
2. I'd forget about it.

Tain't worth all the risk you're facing.
How about just hiding it? Maybe put some lights on the bottom
of the ceiling joists so you can't see above?

Yup. I believe that you are right.

The new hole I cut is actually more attractive than the
random off-center trapezoid placed by the roofers, so
I should stop stressing and move on to more important
things. I thought about placing a grille but I didn't
want to take the efficiency hit.

Thanks for your thoughts on this, Art.
