You are perfectly in line with what Pope Benedict XVI tells us in his homily at the Aosta Cathedral, on July 24, 2009:
“The role of the priesthood is to consecrate the world so that it may become a living host, a liturgy: so that the liturgy may not be something alongside the reality of the world, but that the world itself shall become a living host, a liturgy. This is also the great vision of Teilhard de Chardin: in the end we shall achieve a true cosmic liturgy, where the cosmos becomes a living host.”
“Meaningful evolution” means that evolution aims to form humanity as the people of God’s children, called to enter a parent-child relationship with God, and become Deus-Homo (“one body in Christ”) at the end of time.
I think Christy has very well expressed the same idea in another thread:
If one accepts that the Son of God became human flesh, the speculation that humankind or part of them can “devolve” into a species that is not image of God is preposterous.
