As I just added the front bumper and amber fogs to my order I was thinking of this.Alternatively, you mod the factory fog light circuit so that it can function when both low and high beams are on.
I assume the rigid sae fogs can be wired in with the stock wires. Don't know what the guys that get those and the bullet lights do...
But I'm curious what guys in this position have done. Custom switch or mod the factory circuit.
