*]continuing public revelation,
I don’t think that contradicts Catholic dogma. It is the teaching of theologians that public revelation ended with the death of the last apostle (probably St John) and this may be Church doctrine, but it’s not a dogma AFAIK. In any event, it’s not part of the core of Christian faith.
*]a plurality of heavens,
Are you referring to the three heavens (celestial etc.)? Many Catholics are unfortunately unaware of this but it is Catholic dogma that there will be different levels or degrees of glory in heaven. This was defined in the Council of Florence.
Also, the souls of those who have incurred no stain of sin whatsoever after baptism, as well as souls who after incurring the stain of sin have been cleansed whether in their bodies or outside their bodies, as was stated above, are straightaway received into heaven and clearly behold the triune God as he is, yet one person more perfectly than another according to the difference of their merits.

So there are different degrees of the beatific vision in heaven according to Catholic dogma per above.
If by “god” you mean a being with divine glory, Catholicism teaches that all those in the state of grace are infused with “divine life.” Also read this paragraph from the Catechism of the Catholic Church:
460 The Word became flesh to make us “partakers of the divine nature”:“For this is why the Word became man, and the Son of God became the Son of man: so that man, by entering into communion with the Word and thus receiving divine sonship, might become a son of God.” “For the Son of God became man so that we might become God.” “The only-begotten Son of God, wanting to make us sharers in his divinity, assumed our nature, so that he, made man, might make men gods.”

This glorification that awaits us is called in Eastern Catholic (and Eastern Orthodox) theology “theosis” or “deification” or “divinization.” In the East they say we will share in God’s “energies” but not in his “essence” (I don’t know what divine energies is, maybe one of our Eastern brethren know)
The Mormon doctrine of exaltation is of course a little different. But I don’t think it’s that far off.
What is dramatically different though between Mormonism and Catholicism is that in Mormonism there is a hiearchy of gods where their god is not the ultimate god of the cosmos. But Mormons concern themselves only with the God that brought them forth as spirit-children. This kind of belief can be characterized as
henotheism which is distinct from or at least a subspecies of polytheism.
In Catholicism of course the God we worship is held to be ontologically the ultimate reality, not some kind of local God that we happen to worship.
See above. Eternal progression does contradict the teaching of Catholic theologians regarding the possibility of merit ending at death. But that isn’t a dogma (infallible teaching).
*]Jesus was conceived by the Father and not by the Holy Spirit,
In Catholicism it is IIRC dogma that all actions of the Trinity “ad extra” (that means outside of the Trinity or inner Trinitarian life) are performed by all three divine persons. So the humanity of Jesus was according to Catholic teaching created by the action of God the Father, God the Son, and God the Holy Spirit. I wasn’t aware of any Mormon teaching regarding Jesus not being conceived by the Holy Spirit.
*]the Holy Spirit has a “spiritual body”,
Do you have any reference for this? I was under the impression that that they believed he did not have a body yet.
*]‘As man is, God once was. As God is, man may become.’
As I said they worship a local God and they don’t have doctrines about this God like divine immutability. As for becoming God see what I quoted from the Catechism above.
To call Mormons Christians implies they hold to the essentials of Christianity – what C. S. Lewis termed “mere Christianity.” The fact is, they don’t.
They believe their God is a loving God as we do. That alone makes their religion near to the Christian one. Fr Raniero Cantalemessa, preacher to the papal household – at least he was under JPII, I believe he still is – once said in a homily that if all the copies of holy scripture had been destroyed and there was but one left and it too had been all but destroyed in a fire with just one sentence from the 1st epistle of John remaining “God is love” that the whole Gospels, the whole scripture, would still have remained intact (I am heavily paraphrasing what he said, but it was something to this effect)
