Alternator upgrade

I really like the idea of the http://ecomodder.com/forum/showthrea...tor-33199.html and its low cut in voltage.
The wye wound 10 and 12 series SI alternator have a fairly low cut in speed in factory configuration, between 1000 and 2000 RPM. With my mods, a little lower.

But sometimes solar panels and a little alternator just don't cut it when you just need almost unlimited power. Like a bond villain.
The 1950s design SI series alternator was never intended to run an air compressor, electric pumps, a power inverter powering a welder, hydraulic power unit, light bar or charge LiFePO4.

I would like to upgrade the suburban alternator to my special oil pan 4 blend of CS144 or AD244 alternator. A stock AD244 alternator can make 250 amps, a stock CS144 can make 140 amps. But they are delta wound and don't cut in until over 3000rpm.
Then was thinking my only accessory in the suburban will be the alternator. So I could put in a second one. The gigantic AD244 alternator will take around 4 horsepower to free spin at speed so I will just leave the belt off it and powered down until I need it. All I would need to make it fit is a bracket and some wiring both of which I can do.
The stock pulleys would over drive the alt by about 1:3.

My special blend alternator would be externally rectified and regulated with a max of 10 amp of field current, with provisions to turn it into a DC welding alternator.
