Any guitar can be repaired, no matter how bad the damage (short of burning). The question is, how much will it cost. While I understand how much your guitar means to you, as others have mentioned, the repair costs for this damage is not going to be cheap, and could easily cost double or triple what you paid for the guitar originally.
one thought is to see if you could find another severely damaged guitar, where the damage is confined to the body. It doesn’t have to be the same model (although probably best to at least make it a Guild). Then instead of piecing together a lot of little bits, the neck, or a large part of it, could be used in place of the damaged parts.
There will still be a cost for the donor guitar and the labor, but it might (might!) be cheaper than a replacement. That will depend on what need to be done and who’s doing the work. It also won’t be cheap, and may still exceed the cost of a replacement, but it will certainly be better than repairing what’s there.
You’ll have to endure a stream of “why not replace it with this model instead” replies as everyone offers up their favorite. The silver lining is that there are plenty to choose from, but new and used. Used will offer the bigger bang for the buck, of course, and you may be able to find your exact model, given a little time to look.
But if this is your only guitar, you may want to try whatever fits your budget and is available quicker.
As wrenching as it is, I do feel that replacement is a better way to go in the long run.
