Top up 34k is enough to get her because you will get 34k gold + 17k (rebate) +1k (Halloween carnival)+ around 200 (Super gold wheel) = 52,200 gold and by spend them all you will get 26,100 points + 34,000 points from top up = 60,100 points and you are ready to go.
if my understanding of how the event works is right top up 40k and get 40k points, then spend it all and get another 20k points/ which would give you the 60k you would need for her
