I thought that the safety in ESC's was designed so that if the throttle was applied instantly, then the ESC would deliver power incrimentally (or as fast as it could). Either way, your original plan should work. You might even want to try a slide potentiometer to avoid the gearing situation

They make those?

If you are willing to do that, you could probably just switch the potentiometer for an spdt switch like the ones used in nerf blasters normally. I've never tried it, but it might work. Someone should be able to back me up (or not) on this.

The only problem with this is that if I replace the potentiometer with a button, the ESC's have a saftey that will prevent the motors from spinning up. The ESC's need a pulse that tells them to increase the motor's rpm incrementally rather then a signal telling them to increase the motors to full rpm all of a sudden. For example, if you plug in a lipos to a power system of an rc plane or quadcopter etc, and you bind the transmitter and receiver with the throttle stick at a position besides zero throttle, the motors will not spin up to prevent any accidents. Sorry for my bad sentence structure and grammar as it's midnight and I'm tired.

Do you have a link to the motors. If you do, that way we might be able to help you find a solution. Other than that you could run your pusher on a separate battery pack. 4-6s is kinda excessive 2-3s is more normal

I think I'll just use a separate power source from the flywheel power source to keep things simple.

180's will increase the maximum torque output. This will increase the range of sustained fire, due to the spinning parts having more mass.
 
Increasing the voltage will increase the speed at which the motors spin, increasing initial range and rate of fire. That's why Rapidstrikes with a 3S LiPo (2x normal voltage) can spit out darts faster than a Magstrike.

I'm planning on using a 4-6s lipos since I'm going to be using brushless motors, so can I limit the voltage going to the pusher to the equivalent of a 3s (11.1 volts)

You can use a servo tester instead. It requires no coding you just need to hook it up to ESC's. The only downside is that now your trigger is a potentiometer and you need to twist to fire.
 
This is the one I have. It seems they don't make it anymore but it might fit better so you might want to find something similar.

I can use a servo tester and still use a button to spin up the motors. All I have to do is unsolder the potentiometer and extend its length by soldering it to wires, then replace the knob with a gear so that when I push the modified button it turns the potentiometer. I'll also have a spring in there somewhere so when I release the button the potentiometer rotates to its original position.
