I have gone ahead and designed a PCB this evening. I will likely sit over it for a couple of days before sending the design in for production, to make sure I am satisfied with it. The old IF can measures 0.75" x 0.75", so I designed this to be 0.725" x 0.725" to be inserted into the gutted can. Have a look at the finalized schematic and PCB 3D model images.
For grins, I did also try connecting the prototype the design with the coupled inductors to the radio. It wasn't tunable at all, unlike the success I had with the individual inductors. So I will be moving forward with the individual inductor design.
