D'oh! Should have known when I ordered my rear pair about six weeks ago. GLWS!
Which calipers / pads are giving you the over hang issue? I tried enlarging your photos to see the wear pattern to determine if it was inner or outer over hang on either the front face or rear face or both but could not get enough detail from the resolution of the photos. I plan to run mine with Wilwood FNSL4 calipers and 7416 pads.

I am running Wilwood calipers with 7416 pads which have more pad depth than stock. If you look closely at the front face you can see pad transfer down below the friction surface into the scallop area of the rotor tabs.

I pulled my parts and took the caliper to them and yes you are correct about the pad overhang. Considering the huge weight savings of approximately 8 lbs each for the Girodisc #A2-324 C6 Z51 J55 13" rotors weighs 12.3 lbs each vs. say a stock replacement C6 Z51 J55 13" rotor (plain-not cross drilled) Centric #125.62096 which weighs 20.2 lbs, as well as the fact that the Girodisc rotors also retain the rear parking brake functionality, could a non-optimal solution be possibly chambering the inner and/or outer edges of the 7416 pads?

Porterfield or other places can cut existing pads to new shapes. I’ve used them for multiple projects to make pads for a caliper when the exact size isn’t offered by a preferred supplier.
FYI the performance afx rear 2 piece rotor has an appropriate friction surface for a deeper pad. I used them on another project and this time thought I would give Girodisc a try… I have the afx rotors on the car now.

Odd question - do those center hats allow use of the factory e-brake? I only ask because they do seem to wrap inward as though they provide a surface for the pad.

Much appreciated. I'll keep this as food for thought for my C6Z rears. Not that it would be needed on a street car ever, but if I shifted to the AP front 2-pieces up from the C6Z sized singles from KNS then why not?
Thanks - I didn't think retaining the e-brake would be an option on 2-piece rears.
