With my little technical knowledge the following sentences are just a suspicion...
The surface where the pressure will rest on on the lug nut is the same, whether it is bolted straight up or a little angular. The only difference is, how the force which holds the nut to the bolt is applied. If the difference in the bolt pattern is .65mm this will transfer to a distance of .325mm for each bolt. This will result in an angle of about let's say 1-2° in which the force isn't applied axial. Torque the nut a little bit more than normal and that should do it.
If those lug nuts were a faulty design, they wouldn't sell them in Germany where you can drive as fast as you want on the Autobahn.
That's only my logical conclusion. I, for myself, wouldn't try it out on the highway, etc. without an expert assessment (e.g. TUEV-certified). I wouldn't want to loose a wheel while driving 80mph...
Hope you get what I intended to write
. My english is just really really bad nowadays due to lack of exercise.
Edit: Ok, googled a little bit. Those lug nuts are only TUEV-certified if they are used with special rims that demand them. Otherwise you won't get through inspection... For safety reasons this would be the time to say this idea was a dead-end! Safety first (yours' and for other ones')!
