Just a small correction here if you will. My corrections are addressed to that which I underlined in your post and excerpted below.
"
However, after Saul was converted to Paul and began preaching Christ, the other apostles began to see that he was indeed the 12th apostle, and the replacement for Judas Iscariot."
Corrections in order.
Saul was not converted to Paul. Saul was referred to as Saul after the Damascus road encounter.
The Book of Acts chapter 13 and verse 2 As they ministered to the Lord, and fasted, the Holy Ghost said, Separate me Barnabas and Saul for the work whereunto I have called them.
Saul was not chosen nor accepted by the Apostles as the 12th Apostle. Matthias replaced Judas.
The Book of Acs chapter 1 and 23 And they appointed two, Joseph called Barsabas, who was surnamed Justus, and Matthias.
24 And they prayed, and said, Thou, Lord, which knowest the hearts of all men, shew whether of these two thou hast chosen,25 That he may take part of this ministry and apostleship, from which Judas by transgression fell, that he might go to his own place.26 And they gave forth their lots; and the lot fell upon Matthias; and he was numbered with the eleven apostles.
There is no scripture wherein it is stated the Lord converted Saul's name to Paul.
