Stacked Crafting (skQuery)

[EndxrMqn_]

I've been beginning to use skQuery for custom crafting recipes. I am very new to skQuery (but I have been using skript for years) and I was trying out a few recipes when this worked:

on script load:
    register new shaped recipe for iron sword of smite 3 and looting 3 named "&cVorpal Sword" using 2 bone, iron ingot, 2 bone, iron ingot, rotten flesh, iron ingot, 2 bone, iron ingot, 2 bone

The recipe works fine, but unfortunately it leaves four bones in the corners of the crafting table (which makes sense because it only uses one of the two bones).
Is it possible to make stacked crafting recipes like I have above (without the issue I am describing)?
Sorry in advance if this is a stupid question.

EDIT: I realize why the code wasn't working. The numbers before the "bone" are useless. Still, is this possible?

EDIT 2: I've tried this:

on craft of iron sword:
    if the name of the item is "&cVorpal Sword":
        remove 4 bone from the player's inventory

also didn't work, presumably because what's in the crafting table doesn't count as the player's inventory.
