The biggest problem with ply tanks it that eventually the moisture or a leak will rot the wood and ruin the tank. And in a ply tank lined with fiberglass the fiberglass if thick enough should provide ALOT of the tanks strength. Why not just build a frame out of metal and then use thin sheet metal to line it and then cover in fiberglass? it would last forever and still be pretty cheap because you wouldnt have to use stainless.
seems like a good way to get a longer lasting tank for similar $$
