Besides that such an event will get high public attention to the lottery and will raise the ticket sales .
I disagree.
Winning a "jackpot" that is significantly lower than the advertised "estimated win" and then only being able to access 50% of this (already very reduced) winnings will most likely not boost ticket sales.
What it might do is show how ridiculous the current setup is and create a huge bunch of drama because the conditions are not clear (or mentioned at all) on the site.
