From the Field Test, (I don't have a Khador deck yet)
Quick Work -
When this model destroys one or more enemy models with a melee attack during its combat action, immediatelyafter that attack is resolved this model can make one normal ranged attack. Attacks gained from Quick Work do not count against a weapon's ROF.
I'd rename it to something like "The ol' 1-2" and change "destroys one or more enemy models" to "hits".
You might want to give him a generic grenade anyway, ala Dougal MacNaile.
As far as a feat goes, here's something I came up with:
"Enemy small- and medium-based models within the number of unspent FOC on Ballard in inches suffer a POW 14 damage roll and are slammed d3" +1'' per unspent FOC directly away from Ballard. Models are slammed in an order determined by Ballards controller. All damage rolls are simultaneous. Enemy large-based models within the same area suffer a POW 14 damage roll and are knocked down."
