So goes my logic.

I see two points here:
Q) Is the loss of this system going to actually be noticeable in my fuel economy? Because I'd really like to have AWD
A) Yes, I think it will. The amount of loss in fuel economy will be
directly proportional to the amount of power that you add to the front wheels. If you only wanted 1HP up front, it would be miniscule. You could add 200HP up front, but you probably couldn't go 20 miles on a tank of gas trying to turn those generators. And, the more power you try to send up front, the less total power your car will have - because the system operates at a loss!
Q) Can I prevent my motor from lugging this way?
A) Lugging happens when your load is too high. This will
add load to the engine - you're burning more fuel, after all, and your gas mileage is going down by doing this. The generators don't run for free, they're leaning heavily on the gas engine! If anything, it will lug worse.
You're asking to put extra load on the gas engine to give it to front motors, but you'll always load the gas engine more than you get from the front motors.
