a Bug made it possible and theoretically i could play dungeons i create myself with it. Ui fits and beside the following is sometimes weird when being the fake hero it feels like it could be in the game like this. Also you could make a run challenge with it where instead of 1v1 you can also have 2v2 and faster ones reaching the end are the winners. Wouldn't that be cool?
Not saying i even have 1 friend, but...possibilities!
