upgrade alternator question?

I really like the mopar alternators with the exception of the low rpm voltage drop, or amperage. What ever.
I have run 2 regular 80s gm alternators on 2 separate mopars which eliminated the voltage drop at idle. I also added a fat wire from the alt + to the Batt +. Simple mod back when I was a kid. I totally dont like the look of a gm alternator but they seem to work perfectly and are practically free out of a mid 80s car at a junk yard.

I think you can hook up one of the wires out of a GM alternator to the factory Alt light on a mopar to make that work properly. Pls correct me if I am wrong..
