It can be done but is a lot more difficult since the system does not use relays, instead it uses FET's feeild effect transistors as the switching devices and they are built into the SPDJB box.
I don't know why you would want to do this anyway, fog lamps have a very short feild of depth and illuminating them at the same time as the high beams will not really improve your forward vision.
If you look closely at the fog lamp the chrome plating inside it at the bottom has unchromed areas to further define and shorten it's beam pattern. In my view it not worth the time and expense of this excercise.
Now that you have your car - how do you like it ?

My plan for the spring is to install a front fascia with fogs (like the Roush)and replace the factory fogs with some driving lights, something like this --> My Hella Lights :: Rallye 4000i Compact Xenon (yes I know, "off road only" )
I haven't researched what will fit, but the OEM fogs are pretty big, so I'm sure there should be something that will work.
On driving lights I've installed in the past, I've used a double throw switch, set up as on-off-auto; such that auto come on with the high beams. Not sure if the HID lights I linked are suitable for repeated on/off duty if they were slaved to the high beams. Might have to stick with powerful incandescent.
