Maybe you could try thinking about this situation a little differently.
Using the case of you, two other players on your left, and six noshows, ignore the noshows. Treat the blinds as being posted by the player furthest left.
One difference might be that, since that player won't really be posting the blinds, the player might not be as protective of them. Also, since it's a three player game, you would play hands of a lower quality than you might in a nine player game. You would also need to become a bit more aggressive because, in a three player game, you're starting to play the player more and the cards less.
