I do radius the posts on the lil/jr series pickups, just a bit. I don't know that I follow the neck radius exactly, but they do get tweaked a bit in the middle.
I set up a customers Lil '59 to a vintage Strat pickup stagger one time. It was divided by three since the Lil series are a third the size of a regular strat pole piece. I set one side up for righty then the other side up for lefty. Got a REALLY cool sound out of it. Alot more "Strat on steriods" kind of sound than a humbucker.
