Bishop Tom,
With this vision I think you are certainly opening up the field to some healthy reflections. 
Underlying it all, in my humble opinion, lies the root fallacy of “clericalism” and it’s concomitant belief: “there is an ‘ontological difference’ in human beings raised to the priesthood”.  When Peter referring to all members of the Church says, “You are a chosen race, a community of priests” he obviously is not opting for a “clerical state with an “ontological difference”.
