Here are my thoughts on glass.

First they will be heavier. Not much, but to me every little bit matters.

You would have to have 4 holes drilled in every piece. Not something you will be able to do at home.

You would probably need rubber isolators and a clamp up pad on the nut side to keep from breaking them as you tightened them up.

And finally at least for the side wings they are more exposed to the aerodynamic loads, so I would worry about them breaking at the attach points.

Just my thoughts.
