I think if 2h gets a nudge that works for every attack direction such as the 1h nudge, but is still as useless as the pummel nudge then that would be absolutely fine.
But giving 2h a nudge that is useful, such as the pole shove nudge, the 1h punch nudge, or the shield bash nudge would make 2h way too overpowered. It already has the most advantages over pole and 1h, does not need another one.
