If you're OK with exceeding AR15 mag constraints, then all bets are off. Let the military define a set of requirements and design a cartridge to it.
The 6.5 Grendel's genius is the performance it gives from weapons currently sized for the 5.56 cartridge. One could, I suppose, make a pretty good case for the 65G as is, in terms of performance relative to size and recoil, even with a blank slate. And it's a case I'd be tempted to make if I had a fully developed 6.5 Grendel M855A1 analog.
