Stamp Kick to Sword Snap?

[Plane]

MA81 limits this attack to feet/legs of standing foes, or any part of a lying foe.

Could you treat a sword as a "lying foe" if you were able to force it to the ground?

Like normally you target a FOE with a "takedown" attempt (or 'force posture change' in TG) after grappling, but what if your intention is only to bring the weapon (perceiving the weapon as a character perhaps?) to the earth and not that weird other character who just so happens to have ahold of them?

In terms of setting up the sword to take more damage (you're bracing it in a vulnerable position) I'm also wondering if in Technical Grappling terms you could spend Control Points to add damage when stamping the sword.

This is a weird situation because if a sword were lying perfectly flat I don't really think you could do much to it at all, it's only when it's elevated enough to buckle in the middle that snapping it via a stamp is feasible.
