for the bridge to rotate 2 degrees from a free top to strung up.

If you take a thin piece of wood and temporarily attach at a right angle to your bridge you will be able to measure a 90 degree angle. Now when you string up the guitar and have it tuned you will be rotating the bridge towards the fretboard. For from the Gore/Gilet guitar making books on wood guitars two degrees is a good target.
Might be easier to measure the stiffness of your top by measuring the deflection down when you put a weight on it. I do not have any data on that but if you google it you might find a target. Or if you use a guitar that you like you can measure it. Hope you do not mind my saying, but you have a steep learning curve to build the guitar as you want. Be prepared to do some experimenting before you start your guitar build.
It might be of benefit to you to look up classical guitars made with balsa, lattice construction, carbon fiber. Keep in mind the tension for classical guitars are about half a steel string.
