First of all, the Hero of Kvatch = Dragonborn is false.

Secondly, the Hero of Kvatch would've died in the 200 years period and the artifacts would've been regained by the Daedric Lords or inherited by family members in some way or another.

Thirdly, some of them isn't in Skyrim because the Daedric Lords has a lot more other artifacts to give to their champions, or the artifacts given to the Hero of Kvatch was lost somehow.
