Given that Jesus is likewise God, does it make sense that He would give Simon the name "Peter" solely because of his personality? Or was it meant to signify a change in Simon's role in the salvific plan of God?

Mark chapter 3 show three changed names of the 12.

16 These are the twelve he appointed: Simon (to whom he gave the name Peter),
17 James son of Zebedee and his brother John (to them he gave the name Boanerges, which means “sons of thunder”),
18 Andrew, Philip, Bartholomew, Matthew, Thomas, James son of Alphaeus, Thaddaeus, Simon the Zealot
19 and Judas Iscariot, who betrayed him.

Boanerges is a collective nickname; James and John never actually receive a different given name by which they are known henceforth (as in the case of Abraham, Israel, and Peter).
