That's not a bad idea at all. We could set up a Private table on Party and go all out against each other. Then in the end, the winner(s) could transfer back half of their winnings to the loser(s) to keep it friendlier.
Even without doing a save like that, we should all play together (at these limits). This would definitely be -EV for me though without the save, unless of course you factor in how much this could improve my game against other people.
I'd like to have at least 5 players to do this though... otherwise, it's a different game anyway.
