yea that would work. When you pull the plunger all the way out till it pushes the button then releasing is the same as if you push it with your fingers. No diff there. Some here already did that.
Maybe you could modify this a bit. Since you have to pull the plunger all the way out and making sure that the button is push and waiting for the moment to release it, why not have it all the way o the front and attach a RUBBERBAND on the plunger and switch so when you start to pull it, its already CLOSE and it looks like the more you pull the plunger (thats the waiting persiod to realease), and its time to release at the point, it might feel like the player had CONTROLED the plunger in a way...Hope you got the picture.
