Tbh, This would be okay as a "one time" thing, not a repeatable Chunin Exams like its supposed to be. - Those Exams are repeating everytime, CE1,CE2 and CE3 - Repeat.
Now imagine, EVERYTIME we got a Chunin Exams, the Village is on fire.. its fun the first time, quite boring the following times.
It is an Exam in a game, not an animated scene in your favorite tv show. ' -'
I prefer having everytime different questions, different enemys and different experiences. - Than having the same thing happening over and over.
