Even within the teams/titles mentioned, individual characters would have vastly different power levels.
D&D doesn't just specify character levels. It also locks down how spells work, how often you can use abilities, etc. The designers have specified how the game works. As others have said, Hero is a toolbox to make your own game. For broad appeal and use, you would need to make sure everyone is playing the same game. In addition to specifying specific characteristic values, I think you would also have to specify an approach to power building, among other things. This was mentioned by others, so I will not dwell.
