I think the best approach is to play lower games and take shots at 2kPLO from time to time when you have sth like 20k in your acccount. The thing is that Party 2kPLO is supersoft right now especially if you play at right times of the day. If you nutpeddle you should be able to earn good $$$ with smaller bankroll. Of course I assume that you know how to intelligently nutpeddle in PLO (this includes avoding some good coinflips on the flop) I believe this kind of play still wins money in these games and you dont need so big bankroll for that. Also you can buyin short like for 1k and nutpeddle even more which should be quite profitable.
I feel that to play normal game you need something like 50k though.

Best wishes
