Personally, I'd rather see proof, than depend upon a maybe.
The 7.62x54 is more powerful than the 7.62x51 NATO. It is closer to the 30.06. So the comparison would favor the x54.
The idea is that you can have a light machine gun of acceptable power with much less weight and ammo commonality with your rifles. The comparison should be the RPD in 7.62x39 and the RPD in Grendel.
You could do the x54 comparison for reference, but no way will the Grendel match it, even at long range.
You can demonstrate the weight difference, though. The Grendel ammo will be much lighter than the x54. As a percentage even more than the x51.
