No, the cure would not be broken, for the same reason it wasnt when the hero of Kvatch did it, becuase Sheogorath is Jyggalyg, just like akatosh is Lorkhan.

When Arden Sul became Sheo, he became shoes other, Jyggy. Just like how if one became akatosh, he would also become Lorkhan.

This is explictly shown both in Oblivion's stained glass windows of akatosh, and the statues of akatosh and Talos in Skyrim.

You cannot become one without becoming the other, hence why Jyggylag is not in skyrim hmself, becuase he is currently Sheogorath, waiting for the next greymarch.
