Can't you see that you contradict your earlier idea?

If they will fire at the same time, their explosion pulses
cannot eliminate each other in the way you proposed before.

If they will fire alternatively (as you proposed before),
because engines are side by side, the rotation
momentum from the pulses also will not cancel, 
but cause the ship to rock sideways.
So either way the pulses will be fully affecting the ship.
