If this is your position then God would have to chose to appoint that position to you. You can ask until you are blue in the face, but God is not obligated to make you a prophet.
I believe Paul is speaking only of those who forthtell what God has already spoken in His holy word when he calls us to pray for the gift of prophecy.
God has foretold all future events in scripture. He no longer chooses foretelling prophets today. Those who claim such ability or seek such ability are, in my opinion, seeking self-glory and display narcissistic tendencies that are not in alignment with the Holy Spirit.
I think we have different definitions of prophecy. I do not limit prophecy to forthtelling scripture or foretelling the future. Prophecy is a revelation from God to edify, exhort, and console believers in our present circumstances. Prophecy also convicts unbelievers in a personal way of sin, righteousness, and judgment for their salvation. Prophecy is thus a message from God to believers and unbelievers in our circumstances.
