Yeah, the only difference might be that he wouldn't have been able to plot behind the scenes like he did in the actual timeline, so I don't think he would've been successful.
Granted, he would've started training from birth according to the OP, possibly under Yoda's tutelage given his potential, and his body wouldn't have decayed so much in his later years. If his evil personality were magically replaced, he could end up becoming the most powerful Jedi of all time, or potentially second to Yoda.
