This can be done pretty easily.
The ignition switch does three things- It connects the red and black wires when the bike is on, shorts the CDI to ground when the bike is off, and lights the rear tail lamp when the switch is in Park.
You only need to provide for the first two.
Get a bigass DPDT switch from an offroad truck supply. It should be waterproof and rated for 10A. It will have two common terminals in the middle, two UP terminals, and two DOWN terminals. When the switch is UP, each common terminal is connected to each of the UP terminals, and to the DOWN terminals when it's down.
The switch can be used in a different way than usual for the CX. Connect the two common terminals in the middle with a piece of 16G wire (solder or 1/4" crimp spade fasteners). Connect the red and black wires to the UP terminals. Connect the green and black/white striped wires to the DOWN terminals.
Ignore and wrap the brown and brown/white wires by themselves in electrical tape. Nobody uses that dumb parking light anyway.
When the switch is up, the 12V is connected from the battery to the starter and light circuits. When it's down, the lights are off and the CDI control wire is shorted to ground, stopping the motor.
