Of course "it works"

Get a 4 terminal disconnect, and run two no 14's up front

Break the series from the ig switch feed to the ignition system.

Run the switched ignition output from the ig switch to one of the no 14 wires going to the disconnect

The return no14 coming back from the disconnect keys a relay, and the relay then fires the ignition system.

You don't even need a relay if you use MSD, just use the small red MSD energizer wire.
