The Czech 7.65x45 is a shorter/thinner variation of the same idea. Just use a 7.35x51 Carcano, neck to whatever bore you want, then push the shoulder back and shorten the neck. 130 grains at 2500 fps for 2450 Joules. Once you have the idea, the form of cartridge can be produced from any source. See the 6.8x43 Remington SPC based on the .30 Remington.
Once a military decides to accept the idea, it just requires the engineering and determination. The Ribeyrolles was abandoned because the post-war French Army changed its requirements once the pre-war long service officers took over designs.
I forgot, the experimental 7x44 was based on the 6.5x51 Carcano.
