[Reasons omitted.] Well, I think it CAN be done. All an IBM joystick is is a couple of variable resistors hooked to the joystick. When the stick is full left, one pot is 0 resistance; when it's full right, the pot is 200k ohms (or something like that - I don't have the exact specs in front of me). All you would need to do would be to re-wire the PC board inside the Atari stick such that full left went straight through, a full right went through a 200k resistor, and analogous connections for up and down. You'd also have to rig some way for the stick to read 100k ohms in each channel when centered.
