Nice theory, just not very likely historcially.

(1) How and why would Paul have converted, if he was persecuting the church as his own writings (which no one disputes) tell us and there was no preaching of the resurrection? There would be no reason to make this move.

(2) When Paul converted the church had no power. Jerome was not reponsible because the 4 gospesl, Acts, and the Paul;ines were in use as canon before Jerome was alive. The church was a minority religion in a world full of options until Constantine, but the core of the canon was in place before that.

(3) Jerome did not corrupt the gospels. We have evidence of what their content was before Jerome was alive.
