I would have thought the electronic locking central and rear diffs 2007+ would have made a difference to the ability, but yeah always going to be limited by the tyre/rim selection.
Random thought but would Jaguar rims of similar vintage be compatible given the shared parentage at that point and commonality elsewhere? Suspect there may have been Jag options running 18" but with big calipers too if the offsets and stud patterns etc would work.
