Nobody makes a production fender that sticks out THAT much. And I can say from experience that 4" wider fenders on each side of your JK could be an issue in and of itself. I have River Raider tube fenders at the stock width (I've got stick out too, not as much as you though!) and I already have a hard time squeezing between some trees. JK's are quite wide already, tires smoosh a bit, but solid fenders might get you trapped, plastic ones might tear off.
If you REALLY want total width coverage regardless of that I'd look around locally for a fab shop to make you a set, they can make a template if you remove one of your stockers. My fenders were WAY overpriced for what I got (AKA having to redo ALL the outside welds), when I was in my buddy's shop his boss figured they would have made them for half what I paid originally.
Another route, I don't like the look of them, but might even do it myself if I get a ticket, is to install one of those bolt-on mudflap kits that have a removable bar for when wheeling. That way you should meet the coverage specs.
Oh, and with the Xenons, anything in the flat-ish fenders makes your tires look like they stick out even more. I know it sounds dumb because the stockers have that lip, but my fenders measure exactly the same from body to edge, but my tires look very bulged out.
Also, am totally jealous of your wheels.
