There are poly-locks with different diameter bodies. But, I don't know that any of 'em will have as much pivot ball contact as a stock nut.
I suppose you could use a hardened washer, under the poly-lock, if you think that more contact would somehow be better.
I've never read of a problem, because of using thin wall poly-locks. I assume the pivot balls are kept from rocking, by their contact with the rocker stud. So, I don't think the diameter of the hold down nut would change anything. The only function of the nut is to hold the pivot ball down, when the pushrod comes up.
