If "equivalent means essentially the same OK..if however "equivalent" means 
the same then..... Nope don't work. :-)
 2/0 pin circumference is .88548 and 4/0 is .91374.. a difference of 
.03816....not much difference but there it is................in order to make 
the same pitch change using a 2/0 pin as made with a 4/0 pin the 2/0 pin will 
have to move 1.0319 farther than the 4/0.
(check my math, and reasoning, though!:-)
 I agree that wear from tuning plays very little part in pinblock failure.
