I'm too late to help on the bridge plate question, but if it's any help for anyone else here's a quick shot of a small body I'm doing just prior to closing the box.
When I get done with this one I intend to post the CAD print of the entire instrument. It's a bit unusual as an all mahogany 14 fret with deep unbound body with an arm bevel. It's slightly smaller than a 00, but not "parlor-sized". X brace and tone bars are 5/16" wide but relatively short, so it's not as over-braced as it might appear.
