I had exactly the same question when I wanted to fit wolf wheels to my 1985 110 (V8 Csw), so I asked my mate. This chap worked for 30 odd years in a research environment as a precision engineer +, the + bit being that he would design and make stuff to enable precision engineers to make stuff, if you see what I mean.
Anyway he was meant to be rather good at it, so I asked his opinion.
Reply as far as I remember was that ordinary original manufacturer stuff was in reality rather rough and ready, no matter how well they claimed to be making whatever.
As far as fitting wheel nuts, as long as all mating faces were clean of bulky contaminents (grains of sand/mud/rust whatever) then nuts that held the same or greater length of thread as the max dia of the thread on the stud would be well within safety limits. Maybe give them 10% more torque than normal,but no more than that.
Basically, just get on with it. That advice was for me to follow if I chose to do so. If you want to do the same then so be it.
As for the comments above about the military not bothering to change studs when fitting wolf wheels, I can't believe they didn't at least phone LR during a quiet moment and ask if it would work out.
