Jr Admin

How complicated would it be to change the name of the Jr. Admin?
I know I can create a rank to say what ever I want but I can not set that rank to Jr. Admin with out it saying Jr. Admin. Maybe I have overlooked a simple answer for this question and I apologize if I have.
A quote from one of my junior administrators.
"I just never liked the sound of Junior administrator, it has an infantile connotation to it, it should be associate administrator.
advisor or consultant sounds better than junior administrator."
So my question is can I change the name of that rank and still have it function as a JR. Admin?
