Yes, you can pray for "anything"... but if it is not a desire of God's for you, there will be no answer.
Your spiritual DNA is perfect! God creates spirits which are without any Earthly race or nationality. Humans create humans, no matter who has what lineage, President Spencer W. Kimball amplified this when he said, "I am sure that if we can imagine ourselves at our very best, physically, mentally, spiritually, that is the way we will come back."
When we are resurrected, "this moral body is raised to an immortal body. We can die no more."
Can you imagine that? Life at our prime? Never sick, never in pain, never burdened by the ills that so often beset us in mortality? The Resurrection is at the core of our beliefs as Christians. Without it, our faith is meaningless. The Apostle Paul said, "If Christ be not risen, then is our preaching vain, and our faith is also vain."
In all the history of the world there have been many great and wise souls, many of whom claimed special knowledge of God. But when the Savior rose from the tomb, He did something no one had ever done. He did something no one else could do. He broke the bonds of death, not only for Himself but for all who have ever lived--the just and the unjust. When Christ rose from the grave, becoming the first fruits of the Resurrection, He made that gift available to all.
