Yes for the 555, but you'll need to use different value Resistors and Capacitors so it's timing works how you need. You'll also need to use a modified Astable setup so it has a longer off time than an on time, as that's just how the 555 chip work.
No for how to wire it up to the controller. You can't wire the 555 straight up to the controller, and definitely not to the white wire there, which is a ground line, that's not going to press any buttons at all.
I'd ditch the 555 idea and code up a 12F683 PIC and use it instead. You can adjust the timing to pretty much whatever and have it be far more precise. An alternate Tact button or even a switch would be used to run the code or not, so switch on or button pressed it would press the controller button over and over with a 1 second delay as it's coded below. If the switch is on, press button, wait 1 second, press button, wait 1 second, repeats forever. Switch off nothing happens.

If the controller is a Common Ground type (all of the buttons have one side connected to Ground) you could ditch the 4066 and only need the 12F683 for doing the button press. The code would need changed in that case as well.
