Personally i would do the same but without using P6. What op are you using P6 for? Are you gashing the end face and What are you doing with the back face, are you gashing that or just dishing it? Seems like you want clearance and dish down the back like as you would on the end but how would you gash it out?
Have you ever used P7? Do You have problems with clearances in P32? Sorry for all the questions. Hope You find a way around it
