If this is version 3 do you have any pics of your own vehicle with your previous and current configurations? And maybe some drawings of what you are thinking. I have no idea how you are going to round the front, adding material? cutting off the tube work?
I am also having trouble envisioning what you are planning for the bottom as well. Are you going to try to keep your approach angle? I can't see how that would be possible with a dam.
What are you using the Patrol for? Weekend trips? Long range touring? The daily commute? Does it need to stay as capable as possible as an off-roader or not?
One thing I would try if I had a proper 4x4 with bullbar is to hang some mudflaps on the front of the bullbar like a semi/road train to deflect the air around your front tires without sacrificing offroad ability. The dirty air off the barwork actually might not be a bad thing with the not-very-streemlined body coming after it. I have heard a couple anecdotes of people adding bullbar expecting a drop in milage but instead getting a gain.
