There are currently about 180 cardinals and not all can vote for the next monarch of the RCC.  While Francis has incrementally upped the numbers, and especially with geographic diversity, he should have made larger batches to dilute the JPII and B16 males. He has the power; why simply tweaking at the edges? He would be on firm ground if each country minimally had a token cardinal.  More universality, catholicity?
What is lacking, even with more cardinals, is diversity of thought.  Males are indoctrinated in green house seminaries.  For them to think for themselves rather than repeat the current
Roman interpretation of scripture, doctrine, morals, etc. will take men who have had an exogenous event in their lives. Despite increased numbers, the status quo will remain.
Missing mass, masturbation, etc. will remain mortal sins. Women, a permanent second class. The Pentecost event will remain fiction.  Numbers do not change make. It will continue as a museum for the growing Nones to visit.
