Yea, I remember that you have a tendency to "thinker" around quite a bit too... that's why your ideas are so good... they have been through thorough testing!!!
The Warns, in their FUGLY housing are certainly pretty big to fit into the stock bumper, though I think it might be done with some mods to the bumper bracket. First it would be necesary to remove the bumper cover to have good access to see how it could be done. However, if necesary, one could remove the sealed lense/reflector from the housing and come up with a way more manageable 6" diameter by about 4 " deep housing that has 2 screw brackets that could be used to mount the light, as well as tilt up and down, though side to side adjustment would still have to be fabricated somehow. I think also that the back of the reflector would need a high heat paint job to further protect it from chipping and corrosion. Like I said, it is alot of work to do!!
SO for right now I have already ordered a pair of the new Phillips HIR 9012 bulbs that will fit right into the oem Hella foglights and put out 1875 lumens for over 1200 hours. I hope that they don't scatter too much light, but it is an asy experiment, If one has the Fogzilla conversion harness, one could use the Toshiba 9011 HIR2 high beam bulb that puts out over 2800 lumens for 800 hours, but again, there might be the problem of over amping the Hella reflector, as well as heat build-up!!! So for now, the Phillips 9012 should be here next week.

ALSO, I am running the Phillips Xtreme Power 9007 which Stern recomended in the oem headlights, and they ARE a definite improvement, as is the modded multifunction switch that I did--

I would also have the option of mounting the Warn 6" reflector/lense in a KC 6" stainless housing (they fit right in!!!!) upside down on the Defiant light bar to keep the lights at foglight level for either the Warn fog or Warn driving light. The KC housings are OK to mount upside down, though they recomend a little silicone on the ones with a weep hole.
I would also have the option of mounting a pair of identical KC HiLites in Stainless on the top bar for High beam supplements.
The set-up would look something like this-- though I am sure that wiring and switching would be pretty intricate.
