No, but your post increased D4 tyre size by 10%. Then you disallow a defender from doing the same which makes it an unfair comparison. 
To match,  or in their opinion better a stock puma offroad a D4 needs:
3000 of wheels   ................. Yes to buy Gordon's 18's
2500-3500 of tyres ............. Nope, plenty of good off road 18" tyres for much less
Suspension lift ................... Nope, in case you had not noticed it comes std.
Smaller brakes ..................  Nope, Gordon's 18's fit std brakes problem is in another of YOUR  posts you speak of "several owners " who have swapped their larger D4 callipers to fit smaller D3 ones and 17 inch wheels,,,, didn't you? That would by your own admission requirements an???:D
Engineering report .............. Nope, Gordon's wheels don't need it.
And don't forget
A Heat gun to fit rubber. :D .. God only knows what your on about. ...
