Will GM 200r4 work with factory floor shift location?

Here's my plan for the neutral safety and reverse light switches. I plan to remove the console on my Cuda and remove the shifter (see pics). Then I'll buy a push button type switch and mount it to shifter bracket as shown in pic. Whenever the shifter handle is in park it will depress the button grounding the wire so the car can start. I plan on using the wire that goes to the middle post on the trans switch. The service manual tells me that the center wire goes to ground when the trans is in park or neutral so all I have to do is extend that wire into the cabin area and connect it to the switch then from the switch to ground. The second pic shows the solution to the reverse light circuit. My manual tells me that the two outer wires on the tranny switch connect when the trans is in reverse completing the circuit to the back-up lights. I plan to buy the lokar switch and mount that goes with the 2004r so when I hit reverse the lights will work. Has anyone tried this before????
