That's basically how I made my transom support for my aluminum boat. It's 20 layers tick, and laminated with Weldwood Contact Cement. Not the treehugger hippie envirornmentally safe stuuf, but the nasty fumes will knock you out if you don't ventilate stuff. I then coated it with epoxy resin after it was cut and sanded to shape, and routed along the top face for the aluminum edging. The layers are a little over 1/8 inch thick, so the transom is about 2 inches thick total, so it supports the outboard real nice. Finding the birch in thin sections sheets at 4ft x 6ft was the trick.
