I really didn't expect to like this. This idea really could work well. I'd probably combine the money ITM because I like the idea of playing deep stacked ITM and I like the idea of short stacks being able to play loosely on the bubble if they have a much bigger stack at their other table.

I think the bonus for surviving both would make this too similar to playing two separate tournies, and is a little too much anyway.

Also, in order to make this work, I think you'd have to have a player's other chip stack under their chip stack at your table. This is very important information, and forcing people to go digging for it while they play two tables would be horrible.

Great idea. I'd like to see it implemented (doubt it will, of course, but I don't think you expect it anyway).
