I would make a fiberglass mold. Put down mold release on the non-injured hood and make a mold of the areas you want to fix (the two corners. I'd only make the mold size like a foot by a foot or so.) To do this you'll put down gel-coat on the non-injured hood and then when that has cured properly (fingerprint test) You apply the fiberglass and resin. You let this cure for about a day or so (the decision for how many layers is up to you, but I'd probably go for 2 or 3, hell maybe even 4, fiberglass is cheap and you'd want the mold to be strong). You then remove the mold. It would probably be a good idea to over lap the edges of the corners so the mold will line up on the injured hood.

Take your molds and clamp them into position on the injured hood (I'd use saw horses or something and have the injured hood on top of the molds). Be sure to apply more mold release inside the molds so they don't stick to your hood after you pour in the epoxy. Once you have everything set up, mix up some epoxy (use the part a and part b kind, not the polyester resin for this) and pour in a small amount into each mold. Let harden for a day or so and then remove the molds. It won't be perfect, but it'll look better than it does now.

P.S. You should probably work on some of these concepts on practice pieces before attempting on the real thing.
