Is there a need for such a tournament?

I'm all set to run the Black Sabbath tournament. The only question is how many people will participate. If at least 10 people sign up, I'll start it. The essence of the tournament is that you're given a save file with a Dungeon castle that's slightly less than half-built, and the heroine Erin. The task is to level up Erin within a month. Whoever levels her up the most wins. The whole point of the tournament is that I think this idea will attract not only hardcore offline players but also casual players because you don't have to complete any quests; you just have to try to gain as much experience as possible. An important note is that only Erin's experience will be counted. Therefore, the tournament requires some skill in playing as the Dungeon faction. Although, if there are suggestions, we can try to create several balanced save files for different castles, but it seems difficult to me.
Share your thoughts – do you like it or not? Is such a tournament needed or not?
If you ask, I can add a preliminary set of rules.
