Some thoughts:
1. The church (really, its bishops) are absolutely loathe to consider even speaking up to discuss changing a practice for fear of being seen as not on the team. The church in general seems to be loathe to change anything! I think of the church as similar to the NRA--the NRA doesn't want to agree to even one tiny, reasonable possible restriction on gun laws--like not selling guns to people with documented mental health problems--for fear of cracking open the door in which a flood of additional demands might ensue.
2. To make priests sacramental ministers the church would have to admit the capabilities of professional lay people. My experience with that? I'm not working for the diocese anymore. Further, I'm a professional woman. They wanted to do things their way, whether legal or moral or not, against professional advice. Until they can get past that (my way or the  highway), don't consider lay admins.
