You're absolutely right, there was a dual circuit hybrid between the single circuit and the 69-70 fully diagonal system. I'm not sure whether your system was used in all countries - I at least haven't seen a car with it.

I automatically presumed Oliver was going for the diagonal system but converting to your axle wise setup of course would be much easier since he won't have to swap out caliper mounting consoles, calipers, mount dual brake lines at the front suspension and so on. All that's needed is a few brake line mod's in/around the engine bay to separate the two circuits and, if wanted, add the differential pressure sensor/failure lamp setup. Maybe the brake light switch is mechanic instead of hydraulic in your system, too?
