That is so stupid that . . gah. I will continue to play this game, then.
I thought of that. I won't set up a complicated diagram, but basically I propose this experiment to disprove your magic-suit notion:
Try standing on your head. How do you feel? Let's see, you get redheaded and feel like your head is bursting from blood flowing down into your face, for one. Oh, I see. Gravity also affects everything -inside- your body. That is, you will still feel a strong dragging downwards within your body, even if the air-bag system was advanced enough to simulate the same amount of pressure all over your body. In short again, the only way to accurately simulate zero-gee is to not allow gravity to affect the body at all.
Edit: Or, that is, the only way to simulate zero-gee is well, zero-gee
