You could remove the hood cut the section out where the hinge rivets are secured to the fiberglass. Remove the small metal that they use to secure the hinge to the hood. Now that you have it apart slip some flat steel about 6" long, 1 1/4 to 1 1/2 wide, probably 1/8 think under the fiberglass so it's hidden. Rivet it on the underside of the fiberglass, use some 3m fiberglass/fiberglass bonding adhesive also to attach securly. Then clean up the section you cut out to re-fiberglass back into position. Drill and tap the new metal for the holes for the hood hinge. Lastly put a rivet back between the bolts (if there was one originally).
IMO this hood is definately fixable with some good ideas posted, but I would follow John's suggestion. Cut the bad area with a cutoff wheel to expose what in underneith and remove the threaded plate from under the hood. Replace it with a longer plate that extends 2-3 inches beyond both sides of the opening. Build fiberglass mat over the open area and support plate, then drill and tap when finished. Be sure to leave reference marks on the hood to help position the new threaded hinge holes. I wouldn't use anything less than 1/4 inch material. It wouldn't be a bad idea to coat it with a rust inhibitor type paint. This will probably be stronger than factory made and if you are careful, not harm the topcoat of paint.
That's an awfully large crack. Have you given any thought to calling your local junk yards to see if they might have any old c3 vettes lying around in the weeds (with their hoods)? My .02.
You could easily repair the hood in an afternoon pretty cheap if you wanted. Fiberglass is a little messy but it not hard at all to work with.
Like mentioned before it is the same stuff that is used to repair boat hulls.
Go to your nearest Home Depot ot Lowes and get a can of fiberglass resin, hardner, and some fiberglass mat (not cloth).
Remove the hood from the car. (help from another person is recomended along with marking the hinge placement on the hood)
sand the area arround the crack (2"-3" inches arround) down a little bit.
When done sanding the area make sure it is relativly clean then cut a few pieces of fiberglass mat to cover the area. 2 layers would probally do the trick.
If the crack does not lay closed with the hood off of the car you may have to use a clamp to hold the hood piece in place.
Mix the resin and hardner as the directions on the product says, apply the resin and fiberglass mat then wait for it to dry.
You can then sand the fiberglass repair smooth and paint it if you like.
The repair could be done for less than 30$.

Your hood is comprised of two pieces of fiberglass bonded together -- the outer shell which gets painted and the inner support panel which amounts to the underside of the hood. Your crack is only in the inner support panel and can be repaired with regular fiberglass repair techniques. This is not a stress area so if your repairs are up to snuff, you will not need additional reinforcement or longer bolts. My hood was cracked in exactly the same area as a result of collision damage. I removed the hood, made a typical figerglass repair (nothing fancy), and reinstalled the hood. No problems and no addtional reinforcement. Use a good quality resin and fiberglass mat. Do not use fiberglass cloth. While it's not a stress area, it is an appearance area so you will want to clean up well and repaint.
