I don't see a way to do that as the limit stop is also the inner guide for the movable die. If such a need ever comes up, I can still dig out the good old Hozan and extend the threads.
As to your other question, my medium range plan is to fully retire off the road (sorta semi retired now) and ramp up my services with a particular focus on wheel building, so as is my wont, I went with the best tool I could afford.
