Your thread is motivating!
I had the same idea, if I can't fully patch the holes, I'll weld some braces at least.

Yes, I think some metal strips bridging the hole would provide a good foundation for fiberglass. I would use the mat material as it's very strong - almost like steel when the resin cures. The added advantages, of course, is that it doesn't rust, it's very easy to conform to any shape and primer and bedliner sticks to it like crazy. I might drill some holes in the metal strips to poke the fiberglass into. Then, maybe apply a second layer of fiberglass. Everything will ultimately be drenched in oil, so no further corrosion should occur. I did a quick bit of research as I was concerned that the oil rustproofing might destroy the bond between the fiberglass and metal. Apparently both the polyester and epoxy resins are tolerant of many fossil fuel based products. Now I just have to find some epoxy resin. Shouldn't be too hard as I live in a fishing community. LOL.
