My intention is not to diminish St. Michael at all but you are confusing the prerogatives of Mary, Queen of Heaven and Earth, with St. Michael. And as Queen of Heaven, Mary commands the Angels and so the Angels cannot do anything, without Mary’s say so. Mary, is the Gate of Heaven, for which St. Michael guards. No good soldier [angel] of the Queen of Heaven, would want himself to be raised to the level of the Sovereignty and Throne of the Queen, this is impossible. St. Michael would not have it. Check out the stories about St. Michael below, very good.
St. Louis De Montfort, True Devotion to Mary #39: “We must not confuse devotion to the Blessed Virgin with devotions to the other saints, as if devotion to her were not far more necessary than devotion to them, and as if devotion to her were a matter of supererogation [extra special devotion].”
St. Louis De Montfort (+1706): “Make for me, if you will, a new road to go to Jesus, and pave it with all the merits of the blessed, adorn it with all their heroic virtues, illuminate and embellish it with all the lights and beauties of the angels, and let all the angels and saints be there themselves, to escort, defend and sustain those who are ready to walk there; and yet in truth, I say boldly, and I repeat that I say truly, I would prefer to this new, perfect path the immaculate way of Mary.” (True Devotion to Mary #158)
Just as the Ark of the old testament was vital to Moses and the children of Israel, the Ark of the New Testament, Mary is also vital and necessary for salvation.
You are attributing predestination with St. Michael instead of Our Lady.
St. Louis De Montfort (+1710): “Blessed Alan de la Roche who was so deeply devoted to the Blessed Virgin had many revelations from her and we know that he confirmed the truth of these revelations by a solemn oath. Three of them stand out with special emphasis: the first, that if people fail to say the Hail Mary (the Angelic Salutation which has saved the world) out of carelessness, or because they are lukewarm, or because they hate it, this is a sign that they will probably and indeed shortly be condemned to eternal punishment.”
St. Louis De Montfort: “… many others have proved invincibly, from the sentiments of the Fathers (among others, St. Augustine, St. Ephrem, St. Cyril of Jerusalem, St. Germanus, St. John Damascene, St. Anselm, St. Bernard, St. Bernardine, St. Thomas and St. Bonaventure), that devotion to Mary is necessary to salvation, and that… it is an infallible mark of reprobation to have no esteem and love for the holy Virgin.” (True Devotion to Mary # 40)
St. Michael, the guardian of the Catholic church, is very powerful. Here are two great stories about St. Michael.

Promote devotion to Mary, the Ark of the New Testament.
From a soul in Purgatory;1879, Retreat in September.
We see St. Michael as we see the angels. He has no body. He comes to get the souls that have finished their purification. It is he who conducts them to Heaven. He is among the Seraphim as Monsignor said. He is the highest angel in Heaven. Our own Guardian Angels come to see us but St. Michael is far more beautiful than they are. As to the Blessed Virgin, we see her in the body. She comes to Purgatory on her feasts and she goes back to Heaven with many souls. While she is with us we do not suffer. St. Michael accompanies her. When he comes alone, we suffer as usual. When I spoke to you of the great and the second Purgatory, it was to try to make you understand that there are different stages in Purgatory. Thus I call that stage of Purgatory great or worst where the most guilty souls are, and where I stayed for two years without being able to give a sign of the torments I was suffering. The year when you heard me groaning, when I began to speak to you, I was still in the same place. http://www.catholicculture.org/culture/library/view.cfm?id=6253
