Why I mention that is that it could possibly be a way to make the alternator only come on during low-load times (when EGR is active)

This might be a good idea, though engines may differ among themselves as far as EGR is concerned, exactly when EGR is on/off should be tested individually. Only you want the alternator on during
high load, not
low, if you are doing it for fuel economy. The reason is that the IC engine is more efficient at higher load, so you will use slightly less fuel to produce the same amount of electricity.
Of course, if you are seeking more power, then it should be as you proposed.
What kind of light did you hook up to the EGR? Any idea as to the current there? I may try this to check when my EGR is on/off.
