Alternative to Hitman Plate?

Picked up an Empire Sniper two days ago and already ordered all of the Inception parts for it, because why not. Upgrading from a KP3, and after playing around with the Sniper I realized I pretty much only use the hitman plate to pump on both markers. Since I am going to be upgrading to the drift kit, and the hitman plates seems to be discontinued, is there an alternative? Am I SOL and have to live without a hitman plate for the rest of my life? :( Thanks for any help in advance.
