Okay, I'll go you one further.  MAKE NO NEW CARDINALS!  Period.  Let this hierarchy go away by attrition.  Hire FEMALE Business Manager, Accountants, Theologians, Treasurers, Pastoral Manager and all the other titles your cardinals are now holding.  If you can't make WOMEN priests, then give them hierarchical jobs.  It's been proven, women are more honest, have more integrity, work harder (for less pay, need I say) and have all the degrees needed -- without the church paying for them.  

Canon law?  Hire a female lawyer.

You get my drift.  Peace.
