Every now and again I pull out my old Bandai Jagdtiger and plan how I'm going to correct it. I suppose I have to lengthen the Bandai lower hull about 1/4", scratch build new upper hull sides and fighting compartment, and use Tamiya Tiger ll hull roof parts, rear, suspension and tracks, use Bandai mantlet and gun, and use some Tamiya Jagdpanther hatches and roof components. That's at least 3 models to correct one! I'm open to cheaper solutions. Are you going to use yours as a master to cast a resin conversion kit?
