I made a percussion pistol in shop class in high school that way. ( yes, the horror!) was easier than tracking down a thick slab locally. It was way easier to inlet the barrel, and shape the stock, as I can lay the flat side down on the bench to clamp it. Wood prices have gone sky high here for some reason. I think gorilla glue will work fine. I made model ship hulls this way, so I thought it may work.
