Well, I'll be damned! It WORKS!
I just tried it, and it works! Woo-hoo!!!

I don't know why I never thought of that before (well, probably because I'm a lot 'denser' than I thought

).
Thank you for this suggestion. You've just made my day!!!
Oh Wait, ... It's not quite what I had in mind.
It changes the aperture only in the bracketing, so it changes the exposure in each (yes, since that's the only way I know how to force it to take the different brackets).
I didn't want it to change the exposure, I just wanted it to change the speed(or ISO) and aperture both to give the same exposure.
I wonder if there's another way to do that?
