the set of hands that we are told to play from different positions work out because they play well against the ranges of hands you are likely to have to play against from the other players. A good set should hold in some way stable, meaning that playing against all people who play exactly the same, they should break even over time.

Maybe I misunderstood, but any set of starting hands will break even against itself. The distinguishing feature of a good set of starting hands is that is is +EV against other sets of starting hands.
