Make Hollow Palm available to all melee skills.

As the title says.
There's no actual reason for it, I just think it would hella fun for a Warrior to be using Sunder while slamming his fists into the ground.
However, I would do this via a unique. Maybe a pair of gloves or a weapon that says gives Hollow Palm, for example: "Players using this item are affected by Hollow Palm."
What do other people think?
