But a double top has a thin skin and is not all that robust. If you have access to a drum sander you can make your own spruce laminate. A laminate back and sides with a non-live back makes sense. But all these construction methods take a learning curve to get right. For doing a single guitar you might need to do two to get right.
One thing I just thought of, I don't know how light a fabric carbon fiber comes in but I have some 0.6 oz/ft glass cloth that was used to cover RC aircraft. Maybe just do a single layer pasted on the inside of a solid top. All you really are trying to do is stop cracks from forming. Or use a nylon fabric instead on the inside of the top. I may have to try this out now to see if it will work.
