I think that with some compromises, we could get there, although lead-free ammo certainly makes it harder.
The barrier penetration doesn't have to match M80 at all ranges, just be closer to 7.62mm than it is to 5.56mm.
Similarly, I don't think that the muzzle velocity, or energy retention at long range, need to match M80 exactly as long as they are in the same ballpark, so that there will be little practical difference as far as the troops are concerned.
