Is it correct to say: "If infallibility were for anyone after the Messenger of Allah, may Allah's peace and blessings be upon him, then Shaykh Raslan — may Allah protect him — would be a prophet, or so-and-so would be a prophet"?

This statement is objectionable and contains exaggeration and excessiveness in praise. The Prophet, peace and blessings be upon him, stated that if there were to be a prophet after him, it would have been Umar. This is due to the prophetic qualities he possessed, the strength of his faith, his devotion of himself and his wealth to upholding the truth, and his detachment from worldly life. Also, because many of his statements aligned with the Quran. Therefore, the claim that someone other than Umar would have been a prophet after the Messenger, if there were one, is an audacious claim about the unseen and a statement without knowledge, and blameworthy exaggeration.
