If add these things and you basically can ensure a much easier time to get 2 or even 3 lines and also reduce the cooldown to 24/48h. The rewards would be adjusted and would be worth nothing. Its a mini lottery you join, if you change the odds and make it faster all you do is dilute the rewards.

Would you do it if the exp reward was only a 10th of what is it now? Or if instead of the 10m mount it dropped to 500k?

Perhaps a 2nd book would be nice, or if you were able to trade 1000/2000 poetics for a new book, some would farm it but a lot of players would simply dismiss it as "ugh grindy"
