So we've seen regular folks be given powers by the infinity stones, people who had powers that were upgraded by contact with a stone, and even created by a stone in the case of Vision. The thing is that these were all incidents involving a single stone at a time.

Now the fast answer to what might happen is to say "nobody could handle that kind of power and they'd die", but is there a real answer? Even amongst individual stones we've seen a variety of levels of power granted, so how would that change if all the stones were involved simultaneously?

By "Empowered" I mean "Given superpowers" by the stones, not used in a snap such as Shulk, Iron Man, Thanos
