Solid fiberglass weighs in around 96 lbs. per square foot versus for instance fir plywood at 36 lbs. per square foot so it is likely that you will add some weight by going with all fibreglass panels to reach the desired stiffness but that would certainly solve the rot concerns permanently. There are bulking fabrics such as fab matt to build thickness with less weight but I have seen so many failures with those products that I would avoid them myself. I would think that you could reach the desired stiffness with a total panel thickness that was thinner than the wood plus fibreglass original so the weight increase should not be as much 3X. You could add solid fibreglass ribs to the bottom of your panels get the desired stiffness with a lighter weight as compared to a plain panel and I don’t think the ribs would interfere in anyway. If the panels in my boat rot out at some point, I would certainly consider a similar solution since the anchor locker is going to be a tough place for wood due to the ongoing humidity and dampness.
Your idea of using the conduit is interesting as it would never corrode. I wonder if it would be strong enough by itself and how to secure the ends so that it could never move? Some kind of a plastic replaceable liner inside of a heavy fibreglass pipe glassed at both ends sounds interesting and permanent.
