/cast [exists,target=pettarget] Kill Command

From what i can tell, it's quite effective (especially that KC doesn't trigger a global cooldown anymore), and it will not allow for firing a steady shot before the autoshot cycle has been finished. Also, if either of the shots crits, it will automatically proc a KC.

EDIT: The complete macro is

#showtooltip Steady Shot
/script UIErrorsFrame:Hide()
/castsequence reset=3 Steady Shot, Auto Shot
/cast [exists,target=pettarget] Kill Command
/script UIErrorsFrame:Clear(); UIErrorsFrame:Show()
