There are two glaring doctrinal issues with this.

First, Christ Himself said that we inherit all things. Scriptures have stated in multiple times and ways that we can obtain all that the Father has. Because of Christ, we can all become saviors on Mount Zion. So the distinction of whether or not we are the Savior for a world is meaningless.

Elder Holland has taught that in order to truly take advantage of the Atonement, we will all have to pass through some token measure of Gethsemane. I believe him, because I know I do, though it is no way comparable to Christ in degree. Whether or not that suffering sanctifie or purifies me is yet to be seen.

So the distinction you are trying to draw is erased by the Savior.

Secondly, we are the children of God. Not "something else." We are joint heirs with Christ, fully and incontrovertibly. The only thing holding us back from our potential to become exactly like Him is ourselves and or choices.
