Was wondering if you're going to do it once again or not?
I wouldn't say it's not viable, just not with the conditions you tried with imo.
If a ticket costed 2hive, it would have been viable or if the prize would have been 50hive or...

Anyway, it will always be some kind of 'chanche' and I would understand if you don't want to risk it finetuning the concept.
