That would be great if that is what Rome preached, but clearly it's not since Rome tells us Mary is a "co-redeemer."
Stop and think about that phrase. Only Christ redeems. The Lamb slain from the foundation of the world. His mother was the earthly vessel by which God brought Christ into the world.
But only Christ redeems. To believe otherwise is idolatry.

You are misinterpreting “co-redeemer”. If you don’t believe me, simply google the catechism of the Catholic Church and read the official interpretation is.
There is nothing in Catholic doctrine that requires one to have the intercession of Mary to Jesus. You can ask her to intercede, the belief being that Jesus would listen to his Mother. But there is no intercession required to talk or pray to Jesus.
