I'm not sure I would want to see G-suits modeled. Given a 1g to 2g blackout threshold advantage, I think it may unbalance the game. It did contribute to the imbalance in the war, no doubt. Should a 109 pull 5.5g at the ragged edge of blackout, but the P-51 behind can pull 7g, it'll greatly effect the result.
My regards,

Think of all the wings that will get popped off though. Worth the price of admission.
