This would move the center of gravity for the boat back 1-2" to 13-14' measuring from the bow of the boat.

This is the most important question to consider when you add a bracket. The bracket shifts weight and buoyancy aft, but once you're on plane, the typical bracket doesn't produce hydrodynamic lift. So it helps keep the scuppers above the water at the dock, but once you're on plane, it forces the hull's center of lift aft which hurts low speed performance.

I think you're on the right track. Determine the correct location for the CG. Don't figure the bracket into wetted length, and use a moment equation to calculate the effect of engine, batteries, console, crew, etc. on CG.
